The Western University product arrives in Hamilton after spending the last three seasons with the Roughriders. He was selected in the second round of the 2011 CFL Draft by the Riders.
Butler started at safety in his first professional season, registering 47 tackles, one sack and five interceptions. Since then, he’s made the transition to linebacker and has excelled in the front seven as well.
Last season saw Butler collect a career-best 60 tackles, three sacks, four interceptions and three fumble recoveries, en-route to helping the Riders win the 101st Grey Cup on home soil.
Meanwhile, the Ticats also signed offensive lineman Steve Myddelton.
Myddelton, a 6-3, 305-pound native of Barrie, Ontario, began his CFL career with the Calgary Stampeders after they selected him with the 30th overall pick in the 2009 CFL Draft.
He played in 37 games over three-and-a-half seasons with the Stamps before being dealt to the B.C. Lions on August 5, 2013. Myddelton suited up in 12 games with the Lions last year.
Before turning pro, Myddelton played four seasons (2005-08) at St. Francis Xavier, where he was named a two-time AUS All-Star, a CIS All-Canadian and was nominated for the J.P. Metras Trophy as the AUS Lineman of the Year.
