Oklahoma State receiver Justin Blackmon said that he wouldn't run the 40-yard dash at the NFL Scouting Combine. However, a source with knowledge of the situation revealed the player might not go through any drills so he can rest his tender hamstring and be fully healthy for his March 9 pro day. He is considered the top receiver in this year's class.

A number of Giants recently underwent surgery following their Super Bowl victory. Justin Tuck had surgery on his shoulder to remove scar tissue. In addition, Chris Canty had surgery on his knee and Linval Joseph also had surgery on his ankle. It was previously reported that tight ends Jake Ballard and Travis Beckum each underwent surgery Feb. 21 to repair torn ACLs.

Adrian Peterson plans to begin running by the end of the month after having surgery on Dec. 30 to repair a torn anterior cruciate ligament in his left knee. "I'm definitely making improvement. I'm starting to get my muscle tone and strength back into the legs," Peterson said. "I'm happy with the progress I've made so far. I'm extremely happy."

Giants offensive lineman David Diehl underwent surgery to repair a broken finger, according to a source. "Well it's good to know that my hand and finger are now fixed. Does anyone need screws?" Diehl tweeted Monday, along with a picture of an X-ray, which shows several screws inserted in the broken finger. Diehl said after winning Super Bowl XLVI that he played most of the season with a broken hand, which never appeared on the injury report.

Rashard Mendenhall hasn't been ruled out for 2012, but the Steelers aren't counting on having the running back next season. Mendenhall, the team's leading rusher for the past three seasons, tore his anterior cruciate ligament in the Jan. 1 regular-season finale at Cleveland.

Benjamin Watson is doing "great" despite landing on the season-ending reserve in December due to concussion problems. Watson played in 13 games and suffered three concussions, including in the preseason. After the third, which occurred against Pittsburgh in Week 14, doctors decided it would be best for him to shut it down. "I'm great. Three or four days after the last incident, I felt normal. I past all my cognitive tests. I didn't have any headaches. I didn't have any nausea. I didn't have any dizziness," Watson said. "With three games left, they just erred on the side of caution and decided to end the season for me. You hate for that to happen, but that's why the doctors are in place. As far as lingering symptoms, I didn't have anything. I know some guys have headaches for weeks. That wasn't my scenario, thankfully. So hopefully, it was just a bad luck year."

Titans general manager Ruston Webster said this week that wide receiver Kenny Britt is recovering well from the knee injury that prematurely ended his season, and should be ready by the start of the preseason. "Kenny's been working hard, and he's coming fast, probably even a little faster than I thought he would, so I'm real happy about that," the general manager said. "We expect to have him out there for training camp. "The good thing about this injury, if there was a good thing, is it happened early. And he's a very strong young man and bounces back pretty quickly from these things."

Rob Gronkowski, who had arthroscopic surgery Friday on his injured left ankle, suffered multiple torn ligaments, according to a report. Gronkowski was able to play in Super Bowl XLVI, but was limited by the high left ankle sprain he suffered during the AFC Championship Game.

Rob Gronkowski had arthroscopic surgery on his left ankle Friday, a source has confirmed. The recovery time for the tight end is expected to be 10 weeks. Gronkowski suffered a high-ankle sprain in the AFC Championship Game against the Ravens. The second-year tight end played in Super Bowl XLVI, saying after the game, "I was good. I was 100 percent out there doing everything they asked me to do."

Peyton Manning has insisted that his recovery is on track, but reports continue to insist he is not. NFL Network insider Jason La Canfora offered up just last week that Manning was dealing with tingling in his arm, false sensations and trouble gripping the ball. Michael Lombardi of The NFL Network concurs. He reiterated Thursday during an interview on "The B.S. Report" what he has previously reported: Manning can't effectively throw. "I think it's unrealistic to assume (he can return). He can't throw the ball," Lombardi said. "I've talked to people who've caught the ball for him. He can't throw the ball to his left. He can't throw the ball across his body, because he doesn't feel it. People who catch the ball for him say he doesn't really have velocity on the ball yet."
