The Rays placed Springs on the 15-day injured list Sunday due to left elbow fatigue.
The left-hander lined up to take the mound early this week in Philadelphia, but he'll instead head to the IL due to the elbow issue. Springs will be eligible to return from the injured list in late September, potentially in time for a couple starts, but there's a real chance he won't return with the Rays six games back of the final wild-card spot. If he is done for the season, the 31-year-old will close the campaign with a 3.27 ERA, 1.36 WHIP and 37:11 K:BB across 33 innings (seven starts).
