The Facts: Bush will visit the Bills in Rochester, New York, on Monday and is expected to sign with the team if he passes his physical, a source with knowledge of the situation told NFL Media Insider Ian Rapoport.

Diehards Line: With workhorse Karlos Williams suspended for the first four games of the season and LeSean McCoy expected to get limited reps in training camp after battling ankle issues during minicamp, the Bills needed a versatile running back to get them through the summer months and early fall. The move makes sense assuming Bush can get the Bills to the point where Williams is back, in-shape and healthy. Bush, who recently turned 31, made it through five games last year in San Francisco, rushing eight times for 28 yards. Bush's arrival doesn't necessarily mean bad news for backups like Mike Gillislee and budding No. 2 running back Jonathan Williams, but it does mean that Buffalo is looking for some right-away professionalism in training camp.
