Chafin (groin) didn't feel completely comfortable throwing his bullpen session Monday, leaving him without a set rehab outing date, Chris McCosky of The Detroit News reports.
Chafin was brought in this summer to operate as a significant piece of the Tigers' bullpen, but he's been hindered by this groin issue to open the season, leaving the team thin with options late in games. It seems as if his season debut will likely come in late April, potentially even early May.
