The Tigers pulled Hurter (back) off his rehab assignment Friday, Chris McCosky of The Detroit News reports.
Hurter isn't dealing with any new injury complications, but the Tigers will pull him away from minor-league games anyway for about a week so that he can work out some issues with his delivery. The left-hander hasn't found much success since he was cleared to play in rehab games Aug. 5, allowing 11 runs (10 earned) on 11 hits and four walks while striking out four batters in just 3.2 innings.
