‘Sirles, 27, is a 6-foot-6, 315-pounder who joined the Bills in September off waivers from Minnesota. He played in 12 games, making five starts, although that total comes with an asterisk. Four of those starts were as an extra tight end in a run-heavy formation to start the game, and Sirles played sparingly the rest of the way. He did make one start at right guard in place of John Miller, that coming in Week 13 against Miami.’
