From Garafolo's report:
The New York Giants' starting right tackle, who left Sunday's 41-34 victory over the Tampa Bay Buccaneers with an injury to his right knee, did not suffer any damage to his ACL, according to two people with knowledge of the preliminary exams performed on Sunday. They spoke on condition of anonymity because the Giants have yet to update Diehl's status, and they cautioned that the results of the MRI performed on Diehl are not yet available.
The report is good news for the Giants, who has been a stalwart on the team's offensive line for the past nine-plus seasons. Over that span, he has started all but four games.
Diehl injured his knee in the first quarter. He walked off the field under his own power, but he was quickly determined to be out for the remainder of the game and did not return to the sidelines. The Giants also lost starting running back Ahmad Bradshaw to a neck injury. Bradshaw is set to undergo an MRI on Monday to determine the extent of the damage. And wide receiver Domenik Hixon also left the game after a hit from Tampa Bay linebacker Mason Foster led to him being diagnosed with a concussion.
