Buffalo Bills running back Fred Jackson left Sunday's game versus the Minnesota Vikings with a groin injury and will not return. Later, C.J. Spiller left the game with a shoulder injury.
Jason La Canfora of CBS Sports reported that Spiller broke his collarbone, and that he will have surgery on Monday. He also reports that Jackson will miss at least two weeks after undergoing an MRI Sunday evening. Because the Bills have a bye in Week 9, it's possible Jackson could only miss one game.
Jackson left the field in the first quarter after a low hit, with the help of trainers and center Eric Wood. He later had to be carted off. Prior to his departure, Jackson had three rushes for 12 yards and three catches for 16 yards against the Vikings.
In the second quarter, Spiller injured his shoulder at the end of a 53-yard run. Those were his lone rushing yards of the game.
Spiller missed only one game for the Bills last year, but spent most of the season dealing with a high-ankle sprain. Entering Sunday, Spiller had 68 rushes for 234 yards. He has not scored a touchdown this season.
Jackson entered Sunday with 227 rushing yards and 245 receiving yards on the season. The 33-year-old is currently the oldest running back in the NFL.
