MRI results on the knee injury sustained by Buffalo Bills running back Fred Jackson were inconclusive on Monday, and head coach Chan Gailey told reporters this afternoon that Jackson will likely miss at least three weeks, but perhaps significantly longer.

Jackson, who was injured on a low LaRon Landry tackle in the second quarter of yesterday's 48-28 loss to the New York Jets, was initially diagnosed with a sprained LCL in his right knee. Monday's MRI did not provide any clarity on the timetable for Jackson's recovery - he'll have another scan in a week or so - which is why the Bills are giving him a loose timeline of three to eight weeks.

Mercifully, the Bills actually have a competent replacement for their latest devastating injury, as C.J. Spiller is coming off of a career outing in which he ran the ball 14 times for 169 yards and a touchdown. Still, going from Jackson to Tashard Choice as the complement to Spiller is obviously a massive downgrade.
