The Buffalo Bills have announced that they have released offensive tackle Kyle Calloway, nose tackle Lonnie Harvey, and wide receiver Aaron Rhea. When tomorrow's deadline for trimming rosters to 75 players passes, two rookies on IR - Marcus Easley and Danny Batten - will no longer count against the active roster, putting the Bills at 75 players.

Calloway was a seventh-round draft pick out of Iowa this past April, and becomes the first drafted rookie to be released by GM Buddy Nix. He had been a mainstay as the third-team right tackle during training camp, outshone by several linemen (undrafted rookie Cordaro Howard among them). There's a chance Buffalo might try to sneak him onto their practice squad.

Harvey failed to make waves at the nose tackle position, where he was unremarkable during preseason play. He, too, has a shot at the practice squad. Rhea, a rookie out of Stephen F. Austin, was signed earlier this month as a camp body, and had virtually no chance of making the roster.

Buffalo will not need to make any more roster moves until this Saturday, when NFL teams must trim their rosters from 75 to 53. Updated (Unofficial) Depth Chart
