BUFFALO, N.Y. -- Buffalo Bills running back C.J. Spiller's season isn't over just yet.

Spiller was placed on the reserve injured/designated to return list Tuesday, a day after having surgery to repair a collarbone injury. That means Spiller will have a chance to return by Week 16.

Spiller and co-starting running back Fred Jackson were hurt in a 17-16 win over Minnesota on Sunday. Jackson is expected to miss four weeks with a groin injury.

The Bills filled Spiller's roster spot by signing Phillip Tanner, who spent the previous three seasons with the Dallas Cowboys.

Tanner had 56 carries for 149 yards and two touchdowns, nine catches for 93 yards and had a special teams role in 40 games with Dallas.

Buffalo (4-3) plays at the New York Jets (1-6) on Sunday.
