"The competitor inside of me didn't want to give up, but you have to be realistic and look at your future," he said.
Although Josh Brock will remain on scholarship, his aid will not count against the NCAA-mandated maximum of 85. Brock sat out last year with a shoulder injury and then suffered his third concussion this preseason. He returned to full contact practice Tuesday but the hitting made his symptoms -- blurred vision, headaches and dizziness -- return.
The contact bothered me real bad, and that's definitely a red flag," he said.
Brock, who started three games in 2002 and 12 in 2003, is the second guard forced to leave the team this year. Bartley Miller, another player who started in 2003, gave up his playing career earlier this season due to chronic shoulder injuries. Miller and Brock are close friends and roommates.
"I'm kind of following in his footsteps," Brock said. "It's definitely disappointing. You really are heartbroken. At the same time, it's not the end of the world."
