Buffalo Bills fans breathed a sigh of relief on Sunday afternoon when head coach Chan Gailey revealed that star running back C.J. Spiller had not broken his collarbone in yesterday's 24-14 win over the Cleveland Browns. We practically shouted for joy when Gailey characterized the injury as short-term.

Today, an official diagnosis is coming forth, with CBSSports.com's Jason La Canfora reporting that Spiller has been diagnosed with a sprained acromioclavicular (AC) joint. (The medically inclined can read about the AC joint here.) La Canfora also gives Spiller's injury a 1-2 week recovery period.

Coupled with this morning's news that Fred Jackson is expected to practice this week, it appears that the team is far healthier at running back than most believed the moment Spiller went down yesterday. Time will tell if the Bills will have Jackson for this weekend's game against New England, but they could very well have both back in very short order. That's a significantly smaller bummer than the bummer in New Jersey today.
