Austin signed with the Bills' practice squad Wednesday, Alec White of the team's official site reports.
Austin didn't garner much interest on the open market after being released by Buffalo, so he'll settle for a spot on the practice squad. He fills a similar gadget role to the one occupied by Isaiah McKenzie (undisclosed) and Jamison Crowder. so Austin's best chance at getting a shot with the Bills during the season would likely be in the event of an injury to one of those two.
