Holliday, 29, is a former sixth-round pick of the Texans back in 2010. He spent two years with the Texans before later being claimed off of waivers by the Broncos.
Since the, Holliday has played for a number of teams including the Giants, Buccaneers, 49ers and most recently the Raiders. However, Oakland elected to cut him loose at the start of the season.
Holliday was an extremely productive kick returner for the Broncos a few years ago as he totaled 1,327 kick return yards, 752 punt return yards and four touchdowns over the course of two years in Denver.
Bullock managed to convert his only field goal attempt and made both extra points to go along with three touchbacks during their Week 10 game, so it would be surprising to see them move on from him so soon.
