O'Hara has a mild sprain of the Lisfranc ligament in his right foot, an injury he suffered during the Giants' win over the Cowboys last week. A Lisfranc injury can keep a player out for a month or longer in some cases. O'Hara hopes to be back sooner than that.
"I think a lot of people associate the Lisfranc with a fracture of some sort or something that requires surgery and I've been told that's not the case," O'Hara said in an interview with Sirius NFL Radio. "I just kind of have my fingers crossed, getting treatment as many times a day as possible, and hoping that I can heal pretty quick from this. More so [I'm] just frustrated than anything that I finally got healthy and now I kind of have to go through another treatment."
O'Hara had been dealing with an injury to his left ankle, something that has been bothering him since the offseason and forced him to miss three straight games this season.
O'Hara came back and played in the Giants' last two games before suffering this new injury to his other foot, which is now in a walking boot.
"It is on my right foot where as I was having some issues, bursitis, in my left ankle," O'Hara said. "It is the other foot now. Apparently I was neglecting it and now it needs some attention."
O'Hara said he suffered the new injury in the second quarter of the Giants' 41-35 win over Dallas. He has been treating the injury since last week.
"It was a pass play," O'Hara said. "I was blocking a guy and my guy twisted with Rich Seubert 's guy and somebody fell on the back of my foot as I was kind of up on my toe. It kind of bent the back of my foot a little bit. That is when I felt it and it kind of got worse as the game went on. I knew after the game that I had done something to my foot."
Adam Koets will likely make his fourth start for O'Hara against Seattle on Sunday.
