Cobb was struck on the side of his head by a line drive off the bat of Kansas City's Eric Hosmer in the fifth inning Saturday. Cobb immediately grabbed his head as he crumpled to the ground.
The Rays have put Cobb on the seven-day concussion list to monitor his recovery before deciding on a timetable for his return.
Cobb took to Twitter this morning.
Want to say thank you to our All-star trainer Ron Porterfield and the doctors @bayfront hospital. Woke up with only a minor headache today.— Alex Cobb (@Acobb53) June 16, 2013
