Jerod Mayo left game with knee injury

Patriots linebacker Jerod Mayo, last year's AP Defensive Rookie of the Year, left last night's season opener in the first quarter with a knee injury and did not return.
In Mayo's absence, Gary Guyton and Adalius Thomas took over in the middle.
“Everybody had to pick their game up when Jerod went out,’’ said Thomas. “We didn’t really know what was going on. Me and Gary went in there and just had to communicate with guys. Guys moving around everywhere. It was definitely an adjustment on the fly.’’
As one might expect, coach Bill Belichick did not offer any additional information on Mayo's status after the game, according to Ian Rapoport of the Boston Herald.
However, Mayo told a teammate that “It’s nothing serious.” And considering he was able to "walk under his own power and without a limp" to the sidelines and then to the locker room, it doesn't appear to be too serious.
More information should be made available on Mayo's status today. The Patriots play the Jets in the Meadowlands on Sunday.
