Rays starter Alex Cobb threw a 29-pitch bullpen session Friday for the first time since getting struck in the head with a line drive, according to the Tampa Bay Times.

Cobb has passed the first set of his concussion exams but is still dealing with symptoms from vertigo. He still needs to pass MLB's concussion-related tests before he receives clearance to play. The Rays have not established a timetable for his return.

"I don't think we're extremely close, but we're moving a lot faster than expected," Cobb said. "Considering what happened, if you would ask me the next day I'd be extremely excited to be 19 days or so back on the mound. It's a great feeling to be able to be back out here, kind of be one step closer to where I want to be and getting into games."
