The Toronto Blue Jays have placed right-hander Shane Bieber on the 15-day injured list with right teres major inflammation, effective retroactively to August 21. Chad Dallas has been recalled from AAA Buffalo Bisons to fill his roster spot, per multiple reports.
Bieber carries a 5-2 record with a 4.53 ERA this season, per Yahoo Sports. The move comes as Toronto sits two games out of the American League wild-card race, per CBS Sports, adding to what multiple outlets describe as mounting concerns over the team's pitching depth during the stretch run.
The timing of the move suggests the Blue Jays made the transaction during their off-day, as MLB Trade Rumors noted that injured list stints can only be backdated three days.
