Monday's NFL roundup: Mario Manningham tries to stick with Giants

East Rutherford, N.J. — Mario Manningham attended his first training camp in 2008 as a third-round pick of the Giants, basically secured of his place on the team’s opening day roster.

Six years later, Manningham is back in Giants camp after a two-year, injury-plagued stint with the 49ers.

This time, the former Michigan star is still recovering from offseason knee surgery, his third in three years, so there’s no guarantee of him being with the team when the season kicks off against the Lions on Sept. 8.

Manningham’s last knee surgery has prevented him from participating in any full drills as the Giants began their second week of training camp Monday. He has not been cleared by the team’s medical staff to resume football activities, so he falls behind on the team’s depth chart every practice and exhibition he misses.

“I don’t have anything made here,” Manningham said before the Giants took the field for their two-hour practice session. “I have to be here like I have something to prove. I can’t worry about what has happened in the past. That’s wasted energy.”

Manningham was one of the stars of the last Giants Super Bowl victory, making an acrobatic 38-yard catch down the sidelines on third down to keep the winning touchdown drive alive in the 21-17 victory over the Patriots on Feb. 5, 2012.

Giants quarterback Eli Manning is glad to have one of his former targets back.

“Mario enjoyed being a New York Giant and had a good thing going here,” Manning said. “Sometimes, you leave and you realize what you had. He left on good terms, went off, had some injuries and now he’s here. I’m glad to have him back.”

Manningham is not expected to see any preseason action until the fourth game in three weeks, giving him little time to make the final 53-man roster.

Extra points

NFL senior vice president of labor policy Adolpho Birch disagreed the league’s two-game suspension of Ravens running back Ray Rice for his domestic violence arrest was too light.

“If you are any player and you think that based on this decision it’s OK to go out and commit that kind of conduct, I think that is something that I would suggest to you that no player is going to go out and do that,” Birch said.

Rice pleaded not guilty to a third-degree charge of aggravated assault and avoided trial by being accepted into a pretrial intervention program in May.

... For the second straight day at Eagles camp, a fight broke out between an offensive and defensive player.

Cornerback Bradley Fletcher took on wide receiver Jeremy Maclin on Monday. Linebacker Trent Cole got into it with All-Pro running back LeSean McCoy a day earlier.

Thomas missed the first five days of training camp following the death last week of his grandmother in Georgia.
