EAST RUTHERFORD, N.J. -- Giants rookie edge rusher Kayvon Thibodeaux sprained the MCL in his right knee in the preseason victory over the defending AFC champion Cincinnati Bengals.
Coach Brian Daboll said Monday that No. 5 overall pick in the draft was being listed as day to day and he hopes to have him back on the field as soon as possible.
It's too early to say whether Thibodeaux will be ready for the season opener on Sept. 11 in Tennessee against the Titans.
Daboll also got bad news on fellow rookie linebacker Darrian Beavers, the team's sixth-round pick.
