EAST RUTHERFORD, N.J. -- Buffalo Bills running back Fred Jackson has been knocked out of today's game against the New York Jets with a knee injury.
Jackson is believed to have suffered a sprain, but the Bills won't know the severity until he undergoes an MRI on Monday.
He was hurt on a 7-yard run off right tackle in the second quarter. Jets safety LaRon Landry hit Jackson low and cut him to the turf.
Jackson limped off the field under his own power. He paced on the sideline for several minutes before the training staff escorted him to the locker room before halftime. Jackson slowly walked off with a towel over his head.
The Bills announced at the start of the second half Jackson would not return.
His backup, C.J. Spiller, made a brilliant 56-yard touchdown run four plays later for the Bills' first points.
