Marcus Lattimore will be patient as he recovers from two major knee procedures.

Lattimore is unlikely to participate in the San Francisco 49ers' training camp in July.

"You know, we come back in late July. Been running sprints, you know, got a chance to get in there with the guys a little bit, that felt good. Probably won't do training camp. You know, just on course with the trainer and my doctor. Get a chance to practice midseason and see what happens."

Arian Foster is downplaying his calf injury that has had him on crutches.

"Yeah, it's going good man," Foster said. "It's just a small calf strain. News is dry in the offseason, so it made headlines."

Foster said he "more than likely" will be ready for training camp.

The Denver Broncos released Willis McGahee due to health concerns, according to a report from the Colorado Springs Gazette.

Santonio Holmes is rehabbing a Lisfranc injury that required two surgeries and limited him to just four games in 2012.

The New York Jets may place him on the Physically Unable to Perform list to begin training camp. 

"He's doing a decent job but we'll see how he is in training camp," Ryan said Wednesday. "There's a possibility he starts out on the PUP, I'm not sure, but he seems to be doing well." 

Ben Roethlisberger underwent minor surgery on the meniscus of his right knee on Wednesday.

"We advised him to get the surgery done to ensure he will be completely healthy for the start of training camp. This surgery will have no long-term effects on his health," said Mike Tomlin in a statement.

Roethlisberger hasn't played a full season since 2008, though he hasn't missed more than four starts in any of them.

Trent Richardson could be held out until August due to a leg injury.

Sources say there is fear that Richardson could sustain a more serious broken leg due to the structure of the leg.

Richardson has also been having migraines.

Jason Pierre-Paul underwent back surgery on Tuesday to fix a disc condition that has bothered him since last season.

Pierre-Paul was trying to manage the injury, but recently decided it was best to undergo surgery.

The microdiscetomy was performed by Dr. Robert Watkins at Marina Del Rey Hospital in Marina Del Rey, Calif., the New York Giants said.

"My back has been bothering me for a while, and even last season I played through some back issues," Pierre-Paul said through the website. "The treatment I've been doing has helped manage the issue, but this procedure is going to get me fully healthy and there should be no more pain.

"I'm going to do everything the doctors tell me to do during my rehab so I can be back playing the game I love at a high level as quickly as possible."

The Giants hope Pierre-Paul is available to play in Week 1.
