The Rays said that starter Alex Cobb will be released from the hospital Sunday, but he won't make it to Tropicana Field for the game against the Royals, the Tampa Bay Times reports. 

There is no timetable for Cobbs' return. Cobb left Saturday's start against the Royals in the fifth inning after being struck in the head by a line drive. 

All tests on Cobb came back normal. He was treated for an issue dealing with draining in his ear, but only has a mild concussion.
