Los Angeles Rams quarterback Matthew Stafford is nursing a nagging elbow injury in his right arm deemed as tendinitis, and the Rams have moved from being a 1-point favorite to a 2.5-point underdog for their Week 1 home game against the Buffalo Bills at Caesars Sportsbook.

The Rams-Bills matchup is the only Week 1 game where the favorite has switched and it also has the largest line movement at Caesars.
