GREEN BAY, Wis. -- Jordy Nelsons return to practice was greeted with big cheers as the Green Bay Packers got one of their big playmakers back.At least for a little bit of practice.Nelson, who missed all of last season with a knee injury, was limited to individual drills Monday and primarily ran routes on air and caught passes from Aaron Rodgers and rookie backups Joe Callahan and Marquise Williams. His goal is simple in his long-awaited comeback: Be ready to play this years season opener on the road against the Jacksonville Jaguars on Sept. 11.Obviously, theres prep that goes into the season with the training camp, Nelson said, but the important stuff is the games, when it really matters.The Packers activated Nelson, entering his ninth year, from the physically unable to perform list last week after he had been out with an injury to his other knee.After keeping his nose in the playbook and paying close attention to the tendencies of defensive backs as he watched practice while he was sidelined, Nelson doesnt feel the missed time on the field will be detrimental.I felt better today, honestly, than what I thought I was going to be, wind-wise, conditioning-wise, of running those routes and being full padded and everything, Nelson said. So I thought that was a good sign.He acknowledged with a laugh that his cameo work on the field Monday hardly constituted a practice. But that was good enough for those seated in the nearby bleachers as they cheered every catch by Nelson, who participated in warmups with the team before Green Bays preseason game Thursday.Yeah, obviously, the fans are excited, Nelson said. Im excited to be back out there practicing and getting ready for Week 1.Nelson, who tore the ACL in his right knee in a preseason game last summer at Pittsburgh, doesnt know if he will be cleared to play any of the Packers remaining two exhibition games. That includes Friday night at San Francisco, where Rodgers could get his first preseason action.Were progressing, said Nelson, then adding, Its a fluid situation of how everything reacts and how we feel.While Nelson being on the field was big news, the Packers solidified another significant development with their offense. Coach Mike McCarthy announced before practice that JC Tretter earned the starting spot at center over incumbent Corey Linsley, who is on the PUP list because of a hamstring injury.JC Tretter has had an excellent camp, said McCarthy, who alluded to Linsleys prolonged unavailability this summer as a factor in the decision.Tretter, who has been working with the first-string offensive line since the first day of training camp, took the news in stride after he was informed by the coaches Monday morning.Itll be a great opportunity, but I dont think the mindset really changes much, said Tretter, a fourth-year pro. Its just continue to grind away and continue to do what you can to get better every day.Game notes Starting S Morgan Burnett (back) remained sidelined. Micah Hyde started the first two preseason games with Burnett out. Brett Hundley, the Packers top backup quarterback, didnt practice Monday after he aggravated an ankle injury in Thursdays game. Backup G Josh Walker (knee) also was out. Second-year LB Jake Ryan returned to practice after being sidelined since early August with a hamstring injury. ... The Packers released first-year G Matt Rotheram and undrafted rookie long snapper Jesse Schmitt. Rotheram (biceps) and Schmitt (broken hand) suffered injuries earlier in the preseason.---AP NFL websites: http://pro32.ap.org and http://twitter.com/AP-NFLJerry Tillery Youth Jersey .

NASHVILLE, Tenn. -- The Tennessee Titans will be without wide receiver Kendall Wright for a couple of weeks as his hamstring injury lingers.While thats bad news for Wright, it opens chances for players on the roster bubble to get extra work at the inside receiver spot until he returns.Wright, the Titans first-round pick in 2012, tweaked his hamstring Aug. 3 and hasnt participated in practice since. With Wright out, veteran Harry Douglas has been getting additional work alongside starters Rishard Matthews and Tajae Sharpe.Douglas started most of last year. But after the acquisitions of Matthews, Sharpe and veteran Andre Johnson, Douglas came to camp needing to stand out to keep his roster spot.Harry comes to work every day like a pro, Titans coach Mike Mularkey said. He hasnt even blinked with anything weve done here with the draft, with signing of players. Hes the same Harry. Hes going to come out here and work and make it a tough decision on us when we have to make up the roster.Second-year man Tre McBride, a long shot to make the roster again this season, also is getting extra work as a backup in the slot to Douglas with Wright sidelined.I think whoever is going to be out there, I trust every single one of those guys and their ability to make plays, quarterback Marcus Mariota said. Whoever is out there, Im going to do my best to go through the read and get them the ball.Wright has been moved almost exclusively to the slot recceiver position this year.dddddddddddd He struggled with injuries a year ago and had a career-low 36 catches.Mularkey lamented the valuable practice reps Wright is missing and said that its not a tear, but its obvious when you look at the MRI that hes got a lot of fluid in that area, and hes probably a couple of weeks from being able to go.Nobody can afford to miss practices right now, Mularkey said. But you have to deal with it. We are, and he is. Hes been really good in the meeting room and been really good with the rehab.While Wrights injury is discouraging, there have been some positive preseason developments involving Titans receivers. Mularkey complimented the performance of Sharpe, a rookie fifth-round draft pick from UMass who has settled in well.He hasnt been intimidated whatsoever by anything, Mularkey said. Everybodys talking about, `When the pads go on, can he beat press? It doesnt shock me that he was capable of beating press. Hes done everything to earn that spot, first of all, and nothing to lose it.NOTE: Mularkey said after Wednesdays practice that reserve safety Josh Aubrey has retired. Aubrey had appeared in one game for the Titans last season. He played six games for Cleveland in 2013 and two games for Houston in 2014.---Online: http://pro32.ap.org/poll and http://twitter.com/AP-NFL ' ' '
