Blue Jays manager John Schneider said Shane Bieber has been diagnosed with a mild-to-moderate teres major injury and will be shut down from throwing for at least two weeks.

Schneider added that Bieber underwent an MRI that revealed the issue after experiencing discomfort while throwing a bullpen session recently. It seems highly unlikely he’ll make it back before the end of the regular season with just over four weeks remaining. It’s a tough break for the Blue Jays, and fantasy managers, since he was pitching much better in recent weeks. He’s not worth stashing in shallow mixed leagues at this advanced point of the year.
