Rodon was placed on the 10-day injured list Thursday with left elbow inflammation.
This comes a day after Rodon was tagged for three runs on five hits and two walks across just 3.2 innings during Game 1 of Wednesday's doubleheader against the Orioles. The severity of the issue is not yet known; according to James Fegan of The Athletic, the southpaw is scheduled to undergo a variety of additional tests in the coming days. Lucas Giolito (hamstring) was activated from the injured list in a corresponding move, while Dylan Covey is set to take Rodon's place in the rotation for the time being.
