The Blue Jays placed Cimber on the 15-day injured list Monday with a right rhomboid strain.
Right-hander Nate Pearson was summoned from Triple-A Buffalo to replace Cimber on the 26-man active roster and in the Toronto bullpen. Cimber opened the season with four scoreless innings and scooped up a save across his first four appearances, but he's logged a 7.50 ERA and 1.67 WHIP over his subsequent seven relief outings. Blue Jays manager John Schneider said Monday that Cimber is expected to resume throwing later this week and could be in line for a "minimal stay" on the IL, per Mitch Bannon of SI.com.
