Dylan Cease has been scratched from his next scheduled start and underwent an MRI on his right shoulder, the Blue Jays announced. ESPN reported that the team is awaiting results to determine if and when the right-hander will pitch again this season.

Sportsnet characterized the issue as shoulder fatigue, while reporting noted a recent velocity dip from the pitcher. Cease leads the American League in strikeouts and ranks second in ERA, per Yahoo Sports. The injury represents another blow to a Blue Jays starting rotation that has dealt with health issues throughout the season as the team continues to compete for a wild-card playoff spot.
