Heaney is dealing with a damaged UCL in his left elbow but is hoping to avoid Tommy John surgery, Yahoo! Sports reports.

EDGE Analysis

Heaney has made minimal progress since landing on the disabled list in early April with an elbow injury, and the latest report indicates he may be dealing with more than just a minor setback. Heaney figures to continue rehabbing his elbow as long as he can, but if he does not show improvement in the near future, the Angels could decide to send him under the knife.
