However, he was injured for most of the 2014 CIS football season. He signed with the Tiger-Cats ahead of the 2015 season, but sat out the whole year due to the ACL injury he endured in 2014. He suffered through two more injury-plagued years in 2016 and 2017, playing in only five total games with the Tiger-Cats.
