Chafin's availability for Opening Day is in question as he continues to receive treatment for groin tightness, Jason Beck of MLB.com reports.
Chafin was scratched from a scheduled Grapefruit League appearance Wednesday, and time is getting tight for him to get back on track and avoid a trip to the injured list. The Tigers brought Jacob Barnes back from minor-league camp Friday, which seems to be a clear sign that they're worried Chafin won't break camp with the team.
