Colts wide receiver Austin Collie says he feels great despite two concussions during the 2010 season. "My body feels great, my head feels great," Collie said in a Sports Illustrated article that hits newsstands Wednesday. "I don't want to be the poster boy for concussions." Collie sustained his first concussion Nov. 7 at Philadelphia -- he was unconscious for 30 to 45 seconds and left the field on a stretcher -- and a second Dec. 19 against Jacksonville. He also was forced from a Nov. 21 game at New England by concussion-like symptoms.

Saints safety Darren Sharper missed most of the 2010 season because of knee and hamstring injuries, but he says he's not done playing just yet. He told The Times-Picayune in a story for Monday's editions that the knee is now "110 percent" and stronger than it was before. "Oh man, I feel like two different people," Sharper said. "No pain, no swelling. I'm excited about the upcoming season, so I can get back to the level I was at in 2009." Sharper appeared in eight games last season but started only one, netting 16 total tackles.

Texans wide receiver Andre Johnson has gotten a clean bill of health after battling a high-ankle sprain in his right foot during the 2010 season. Johnson told the Miami Hurricane that he recently received medical clearance after having arthroscopic surgery on Jan. 12. "I started (training) a little later this year because of a little ankle surgery that I had," Johnson said. "That's pretty much it, but (the lockout) hasn't changed anything as far as me training. I just got cleared by the doctor, but that's the only thing that has held me back a little bit."

Although the NFL lockout has cut off most contact between teams and players, Green Bay GM Ted Thompson said the Packers are able to track the progress of injured players during the offseason. Speaking to reporters in his annual pre-draft news conference Thursday, Thompson said team physician Pat McKenzie is staying in touch with Packers players who are rehabilitating their injuries.

Lions GM Martin Mayhew says Matthew Stafford's recovery from surgery on his right, throwing shoulder is going well, according to an ESPN.com report. Mayhew said Thursday the team received good reports from Stafford's showing at a charity event that was part of Georgia's spring game last week.

Former Alabama running back Mark Ingram insists that his knees are healthy. Ingram said Tuesday reports that NFL teams are concerned about his surgically repaired left knee are based on "false information" with the draft looming on April 28-30. "I don't know where the reports have come from," he said. "I guess somebody wants me to fall down the board. But my knee is 100 percent. It's strong, it's healthy. All the teams have positive reports on my knee and Dr. [James] Andrews has given positive reports on my knee as well. My knee's 100 percent. It's in great shape. All those reports are false information."

Former Clemson defensive end Da'Quan Bowers received a good report on his surgically-repaired right knee in Indianapolis over the weekend, according to a league source. He will visit the Browns on Tuesday and Wednesday. Bowers, widely regarded as the premier pass-rushing end in the draft, didn't even have to undergo another X-ray or MRI because the physical exam went so well. RealGM's Jeff Risdon has the Dolphins selecting Bowers with the 15th overall pick in his latest mock draft.

The Vikings aren't overly concerned about the surgically-repaired hip of wide receiver Sidney Rice. The team is negotiating an extension with the receiver. "I'm sure if we felt any concerns medically that we wouldn't be discussing extensions with him," Minnesota vice president of player personnel Rick Spielman said.

Chad Pennington was scheduled for knee surgery on Thursday morning and Armando Salguero of The Miami Herald reports that the quarterback hasn't ruled out playing in 2011. The longtime Dolphins and Jets quarterback, who is a free agent, tore a knee ligament while playing basketball.

Jaguars running back Maurice Jones-Drew said he's ahead of schedule in his recovery from arthroscopic knee surgery. Jones-Drew, who said he's already able to run, had surgery in January after playing the entire season with a torn meniscus in his left knee. "The knee's doing great," Jones-Drew said Tuesday on his weekly Sirius NFL Radio show. "I've been meeting with doctors everyday, just been pushing through, working through everything."
