He went on to play in nine regular season games and record 13 tackles in his rookie season, both due to Jacobs' continued suspension and injuries to other defensive linemen later in the season. 2004 season Adams remained with the Roughriders for the 2004 season, but he did not play in any regular season games. 2005 season Between the 2004 and 2005 seasons, Adams played indoor football with the Colorado Crush of the Arena Football League and the Peoria Rough Riders of af2. On May 9, 2005, Adams left the Peoria Rough Riders to attend training camp with the Saskatchewan Roughriders. He acted as a backup for the Roughriders throughout the 2005 season.
