Professional football
Jones started his professional career in the Canadian Football League when he was signed by the Saskatchewan Roughriders in March, 2005. He made his debut with the club in Week 10 of the 2005 CFL season. He finished his rookie CFL season with 15 tackles and one quarterback sack. Jones played on defense and special teams for the Roughriders in 2006, finishing the season with 31 tackles and eight quarterback sacks. During the 2006 season, Jones twice recorded two sacks in a game. The Roughriders captured the 2007 Grey Cup, with Jones playing defensive end and linebacker as well playing on special teams. During the Western Final, Jones had two fumble recoveries. Jones played defensive end full-time for the Roughriders in the 2008 season and led the team in sacks with five. Prior to the 2009 season, Jones was traded to the Edmonton Eskimos in return for quarterback Juan Joseph. Jones played in nine games for the Eskimos before being released. After his release, he had offers to join the Roughriders or the Montreal Alouettes, and Jones elected to sign back with the Roughriders. Roughriders director of player personnel Joe Womack admitted that trading Jones had been a mistake: "Eric and myself and Ken admittedly probably made a mistake -- and that's OK to admit that; teams do it all the time." Joseph, the player the Roughriders received in exchange for Jones was released by the club after training camp. Jones finished the 2009 season with 14 tackles. Heading into the 2010 season, Jones was not mentioned among the top contenders on the Roughriders to replace departing defensive linemenJohn Chick and Stevie Baggs, which suited him fine, "I’m always the undersized guy at my position. There are things that I have to do to remain a Roughrider but I know that I’m in a fight. Then again, I’m always fighting." Jones also sees significant playing time on special teams, where he is considered by some to be among the CFL's best. On Mar 13, 2011, Jones signed with the Montreal Alouettes. On May 7, 2012, Jones was released by the Alouettes.
