SANTA CLARA, Calif. -- Chip Kelly is facing the unenviable task of getting his team ready for its next game to stop the worst losing streak in franchise history.Kellys 49ers have lost 12 straight , with the last two coming against teams with 18 losses combined while starting backup quarterbacks. Falling to the Matt Barkley-led Bears and Bryce Petty-led Jets has Kelly trying to pick up the pieces before traveling to Atlanta to play the Falcons (8-5) and MVP candidate Matt Ryan.I think you just have to stand up and fight again, Kelly said Monday.Despite the losing streak thats given San Francisco the second-worst record in the NFL, Kelly said his players are still playing hard.When you look at the tape, these guys play with great effort. They give you everything that they have, Kelly said.The effort wasnt enough Sunday against the Jets. The 49ers surrendered a 17-3 lead before losing 26-17 in overtime. The offense managed just two first downs and no points in the third and fourth quarters, allowing the Jets to wear down Kellys last-ranked defense.New York backup running back Bilal Powell, who scored the game-winning touchdown in overtime, ran for 145 yards on 29 carries, becoming the 10th 100-yard rusher San Francisco has allowed this season.The Jets had the time of possession advantage, 41:55 to 24:30, while the 49ers defense struggled to make tackles in the second half.Kelly attributed the issues on defense to his offense being unable to move the chains.We didnt stay on the field offensively, Kelly said. Thats the biggest thing, we need to convert, keep drives alive, and keep our defense off the field.The 49ers for the day converted two of 12 third downs, where they rank 27th in the NFL. Colin Kaepernick threw for 17 yards on just four-of-11 completions after halftime, continuing an ongoing trend of second-half struggles for Kellys offense.It was a particularly dispiriting offensive effort after San Francisco jumped out a 14-0 lead, making Sunday the third time Kellys team blew a two-touchdown advantage at home this season.Kelly faced questions when the 49ers hired him last winter about his up-tempo offense and the effects it had on his defenses at his previous stops in Philadelphia and in college at Oregon. He said Monday the no-huddle offense is moving slower than it did previously.If you look at us, most of the time were into single digits on the play clock, said Kelly. Theres a lot of times where were working it down, making sure were in the right play and the right protection. So, its not like were playing fast football right now. Its just were not converting when we need to convert and thats the biggest thing.San Francisco also dealt with injuries to key players.The 49ers placed tight end Vance McDonald on injured reserve Monday after he sustained a shoulder injury in the first half. McDonald led the team with four touchdown receptions and was third with 24 catches for 391 yards.McDonald signed a five-year extension with San Francisco two days before playing the Jets. The 49ers remaining tight ends are Garrett Celek, Blake Bell and JeRon Hamm.Receiver Torrey Smith was lost in the second half with a concussion after jumping for a pass and slamming his head on the turf.Smith needed to be carted off to the locker room after lying motionless on the field. Kelly said Smith will begin the week in the concussion protocol. Smith Tweeted after the game, Thanks for all the prayers!Center Daniel Kilgore went down in the first half with a knee injury.---For more NFL coverage: http://www.pro32.ap.org and -http://www.twitter.com/AP-NFLKevin Johnson Suns Jersey .

Any real chance at payback wont come until the playoff. Still, Pittsburgh knows its taut 3-2 win over the Bruins on Wednesday night is a pretty good place to start laying the groundwork. "They are a very good defensive team," Penguins forward Brandon Sutter said.GAINESVILLE, Fla. -- When Florida coach Jim McElwain got to his desk Sunday, there was a folder sitting on top labeled Presbyterian. One peek inside revealed a significant mistake.I was like, `Wait a minute. Somethings wrong here, McElwain said Monday. I dont have disrespect for them, but this didnt look like Presbyterian.Nope, it was No. 16 LSU.Different jerseys. Different numbers. Much different talent.Hurricane Matthew, which forced Florida to reschedule a home game against the Tigers and cancel a home game against lower-division Presbyterian, could end up costing the 21st-ranked Gators a trip to the Southeastern Conference title game. Theres little doubt McElwains banged-up team would have been better off playing LSU last month -- in Gainesville.Now, Tigers star running back Leonard Fournette is healthy , Florida is down seven starters -- including their top three tacklers -- and the game is being played in Baton Rouge.To me, you want to go play somebody at their best, McElwain said. I dont ever look for a win to have an asterisk on it, does that make sense?It might make sense. But its surely not ideal for Florida (7-2, 5-2 SEC), which likely needs a victory Saturday to clinch the Eastern Division. The Gators could still wrap up a spot in the title game with a loss to the Tigers, but they would need Tennessee to lose to Missouri or Vanderbilt.And Florida will be without at least seven starters Saturday, including quarterback Luke Del Rio (shoulder).You can sit and cry about it or do whatever or you can just move on, McElwain said. Thats what weve got to do. You know what, it is what it is. Were going there to play and thats the way it is.McElwain also ruled out center Cam Dillard (knee), left tackle David Sharpe (foot), defensive end Bryan Cox Jr. (ankle), safety Marcus Maye (arm) and linebackers Alex Anzalone (arm) and Jarrad Davis (ankle). Two others, guard/center Tyler Jordan (ankle) and defensive end CeCe Jefferson (ankle), are questionable to play.Theyre struggling with injuries, so its going to be 10 times harder now, LSU defensive end Arden Key said. Either way it goes, if they played here or there, it was going to be hard for them to get the W.dddddddddddd I dont feel like they were going to get the win when we play then or now.Florida and LSU (6-3, 4-2) were initially scheduled to play Oct. 8 at Florida Field. When the threat of the Category 4 hurricane forced the SEC to postpone the game, LSU took a hard stance on not giving up a home game to reschedule.The Tigers said Florida wanted to postpone it because Del Rio was coming off a sprained knee and two defensive linemen looked like they wouldnt play. Now, the Gators would love to have that short of an injury report.That part bothered me a little bit, Florida safety Nick Washington said. They think we had a choice of avoiding this game when theres a hurricane. Not just me but a lot of my teammates, a lot of us had family in places where the hurricane was hitting. It kind of bothered us a little bit, but we had to let it go.What was supposed to be a relatively relaxing week and a game against a seemingly overmatched opponent from the Football Championship Subdivision has become an all-or-nothing affair against one of the hottest teams in the country and in the one the nations least-hospitable stadiums.The Tigers have won four of five games, the only loss a 10-0 setback against top-ranked Alabama, have Fournette at full speed and have allowed the fewest touchdowns (10) in the nation.Florida, meanwhile, continues to struggle offensively and will have to shuffle guys up front again since it will be without at least two linemen. Its a scenario the Gators surely would be able to handle if the matchup -- or the folder on McElwains desk -- really was Presbyterian.Its the biggest game of the year because its the next one, quarterback Austin Appleby said. With that said, we know whats at stake. We want to go back to Atlanta. Thats why you come to Florida. You want to play for championships. Weve got everything that we want right in front of us.---AP Sports Writer Brett Martel in Baton Rouge contributed to this report.---More AP college football: www.collegefootball.ap.org ' ' '
