ORCHARD PARK, N.Y. -- The Buffalo Bills have cleared running back C.J. Spiller (collarbone) to play and he will be added to the active roster this week, coach Doug Marrone said Monday.
Marrone did not commit to having Spiller, who has been on injured reserve with a designation to return, play in Sunday's game at the Oakland Raiders.
"I'd like to see more participation before we make that decision," he said.
Spiller returned to practice on Dec. 3 after missing six weeks with a broken collarbone. The Bills had until Dec. 24 to decide whether to place him on their 53-man roster.
