Allen (elbow), who has been ruled out for Sunday's game against the Bears, logged a limited practice Friday, Chris Brown of the Bills' official site reports.
Allen's return to a limited practice suggests that he could return as soon as the Bills' Week 10 game against the Jets. Alternatively, if the Bills elect to take things slow with the rookie quarterback, Allen could be held out through the team's Week 11 bye. As for Sunday's game, with Derek Anderson still in the NFL's concussion protocol, Nathan Peterman is trending toward earning the starting nod.
