The Facts: With the Steelers poised to pick from a trio of QBs for Sunday's game in Tampa against the surprisingly undefeated Buccaneers, one of them could be unavailable. Per a league source, an MRI revealed that Dixon has a tear in the lateral meniscus of his left knee.

Diehards Line:Three years ago, Dixon tore an ACL in the same knee. According to PFT's Mike Florio, Dixon will be getting a second opinion on Tuesday and determining the next steps on Wednesday. That possibly leaves Charlie Batch and Byron Leftwich as the options for Sunday if Dixon can't play.
