According to reports, O’Day also mentioned that the injuries were not during competitive drills and happened over a short period of time.
The four players that suffered the injuries are defensive back Nelson Lokombo, running back Jonathan Femi-Cole, defensive lineman Freddie Bishop and, most notably, linebacker Larry Dean.
Dean signed with the Riders this off-season as a free agent and was expected to be a major part of the team’s defence at middle linebacker. He has spent four seasons in the CFL, having stints with the Hamilton Tiger-Cats and the Edmonton Elks. Since coming into the league, he’s helped to anchor the defensive units for both organizations from the MIKE linebacker spot.
