Murphy, who just returned to practice Sunday after missing several sessions and Thursday's preseason opener with a groin injury, had to leave Monday's practice early and was seen pointing to the same area while in discussions with trainers, Joe Buscaglia of WKBW.com reports.

This isn't a good sign, especially since the Bills paid so much money to land the pass rusher in free agency. Shaq Lawson will continue to get more first-team opportunities if Murphy is subject to an extended absence.
