ARLINGTON, Texas -- A's pitcher Brandon McCarthy, out for the season after being struck in the head by a line drive. said what he remembers most about the incident was the intense ringing in his head immediately afterward.

"I just remember kinda after, once I was on the ground, it sounded like a jet was flying close by," McCarthy was quoted by ESPN The Magazine. "I could hear just a ringing. It sounded like a jet was about to take off close. I kept asking, 'Is there a plane overhead? What is that noise I am hearing? It was mixed with that and the ringing. I don't remember anything else. But those are the two things that stuck out."

McCarthy, 29, has made an encouraging recovery since he was struck by a liner off the bat of the Los Angeles Angels' Erick Aybar on Sept. 5. The injury required two hours of emergency brain surgery for an epidural hematoma, brain contusion and skull fracture.

McCarthy told ESPN the Magazine he is feeling "good, all things considered."

He is expected to attend Friday's home game against the Seattle Mariners, where he will be honored before the game for being the A's nominee for this year's Roberto Clemente Award.

"It's hard to describe. Concussions are very weird," McCarthy told the magazine. "You just feel a little cloudy and a little bit off. ... I find that with each passing day it gets a little better, a little better. It's positive in that regard but there are just little things you notice where you know you're not quite where you want to be."

McCarthy thinks he might be able to start physical activity in a week or two, and he's hopeful of being cleared to travel with the A's if they make the postseason, though he won't pitch again this season.

He will be a free agent this winter and plans to continue pitching, saying he won't be nervous to get back on the mound again.
