Source: Spiller will be a game-time decision

As of Saturday afternoon, Buffalo Bills leading rusher C.J. Spiller remains a possibility to play against the New England Patriots. The Bills will check out Spiller's injured left shoulder on Sunday morning and he will be a game-time decision, a league source tells the AFC East blog.

Spiller was hurt in last week's win over the Cleveland Browns. He was initially projected to miss 1-2 weeks. But Spiller made significant progress the past few days and was able to practice in a limited role on Thursday and Friday. Buffalo listed Spiller as questionable"on the final injury report.

Spiller was on a tear before his injury. He rushed for 308 yards, three touchdowns and was averaging 9.3 yards per carry. Spiller entered Week 3 as the NFL's leading rusher before his injury.

But the Bills could be cautious and rest Spiller. Buffalo must weigh the short- and long-term risks of playing their most dynamic offensive player if he's not 100 percent. Fellow running back Fred Jackson is expected to return from a knee injury, and that may impact Buffalo's final decision with Spiller.

The Bills (2-1) have won two in a row and will try to beat the Patriots (1-2) for the second straight year at Ralph Wilson Stadium.
