Rays pitcher Alex Cobb has some fluid buildup in his ear, according to the Tampa Bay Times.
Cobb took a line drive to his head Saturday and was diagnosed with a concussion. Manager Joe Maddon said Cobb was dealing with fluid buildup, but that it wasn't a concern. There's no timetable for Cobb's return.
Cobb has a 3.01 ERA and a 3.53 FIP in 83 2/3 innings.
