The Bills signed tackle Thomas Welch and added cornerback Crezdon Butler off the Arizona Cardinals’ practice squad.
Butler has appeared in three games this season for the Cardinals and Washington Redskins. In three seasons, Butler has recorded just one tackle in eight career games.
Welch has played in eight games with one start during stints with the New England Patriots and St. Louis Rams. Welch has been without a job since being released by the Philadelphia Eagles during training camp.
