September 20, 2011 New York Giants Injury Report: WR Mario Manningham suffered a concussion in the game against the St. Louis Rams on Monday night.

“As far as I know, all of the tests, all of the protocol for a concussion are being conducted today, right now,” said Head Coach Tom Coughlin. “He was much clearer when he left the stadium last night. He was much more bright-eyed this morning when he was in, but nevertheless, he’s going through the entire battery of tests that are part of the protocol for someone who leaves the game with any type of head injury. We’ll wait and see what the doctors have to say today when he finishes his exam.”

There have been conflicting reports on WR Domenik Hixon’s injury. It was originally believed to be a knee injury until after the game it was reported that it was a calf injury. Now the Giants are saying it may be an injury to his right knee. Last year, Hixon tore the ACL in his right knee.

“He’s going to have all of the tests done in regard with his knee as well,” said Coughlin. “I don’t have any information at this point in time, but he too is going to be completely checked out…Wherever the discomfort was, it probably came as a result of the fact that they are looking and doing the exam on the knee.”

Coughlin also mentioned that he hopes DE Osi Umenyiora (knee) might return this week. “We certainly hope to see that Osi will be ready to go,” said Coughlin. “We hope to have him on the practice field. Tomorrow is not going to be a full speed practice. It will probably be Thursday before that takes place but hopefully Thursday Osi will be ready to practice. If there is not a setback, then I would expect that.”

That said, an unidentified source told The New York Post, “I doubt (he’ll play against the Eagles). I don’t think he’ll be ready to go. This is a 4-6 week injury, most of the time six weeks, maybe seven. For him to play this week would be pretty unbelievable.”
