Hollister was released by the Bills on Tuesday, Tom Pelissero of NFL Network reports.
The Bills failed to bring in a higher-profile addition at tight end this offseason before giving Hollister a one-year contract with only $137,5000 guaranteed. Dawson Knox remains the team's top tight end and lone receiving threat at the position, with Buffalo likely using some four-wide sets to mitigate the impact of a weak TE group.
