Canadian defensive back Cauchy Muamba is in Regina and the Saskatchewan Roughriders plan to sign the veteran national.
Muamba went to training camp with the B.C. Lions, but he was released among the final training camp cuts.
Muamba was originally selected in the fifth round, 34th overall by B.C. in the 2010 CFL draft. He played three seasons with the Lions, one with the Bombers and the last four of his seven with Edmonton.
The 31-year-old played in 13 games making nine tackles and one interception for a touchdown with the Eskimos in 2017. Muamba won a Grey Cup in green and gold in 2015.
Over 108 career CFL games, Muamba has made 146 tackles, 25 special teams tackles, 10 interceptions, three sacks, one forced fumble and scored one touchdown.
Muamba, the older brother of former Bombers, Riders and current Montreal Alouettes linebacker Henoc Muamba, provides proven starting experience in the backend and special teams ability.
