Twins manager Derek Shelton said that Abel (elbow) had a setback with his recovery after his 20-pitch bullpen session Friday and won't return from the 15-day injured list this weekend, Bobby Nightengale of the Minneapolis Star Tribune reports.
Abel appeared likely to start Sunday in Arizona after completing a five-inning rehab start Tuesday, but he should once again be considered out indefinitely in light of his setback. The Twins will have him undergo an MRI when the club returns to Minnesota to determine the full extent of the issue.
