Matt Shoemaker had surgery Sunday night to stop additional bleeding in his skull after getting hit in the head by a line drive.

Shoemaker was diagnosed with a small skull fracture and a hematoma Sunday after being hit in the head by a line drive off the bat of Kyle Seager in a game between the Seattle Mariners and Los Angeles Angels.

"The fact of the matter is he was conscious, and at least all his reactions were what they were supposed to be on the assessment. I think we could exhale a little bit," Mike Scioscia said. "Just to get him up and walking off the field let you feel a little bit better about what could have been happening. It's tough."

Billy Eppler told reporters that Shoemaker is expected to return to Southern California later this week.

Seager's liner had an exit velocity of 105 mph, according to MLB Statcast.
