It is Miller’s third concussion in less than a year.

Coach Paul Hewitt said Tuesday Miller struggled as he tried to work out on Monday.

"He came out of it just a little lightheaded, a little off-balance was the term he used," Hewitt said.

Hewitt says Miller was driving when he hit his head on a side window in the accident.

Miller, a junior from Memphis, has started 35 games the last two seasons. He suffered two concussions early last season and missed seven games after the second incident in which he also suffered a broken nose.

"Obviously Moe’s issue is somewhat of a concern," Hewitt said. He said Miller’s return is "just a matter of taking time, resting and healing."

Hewitt left open the possibility Miller could be cleared to practice this week.

Hewitt said his Yellow Jackets overall are in good health as they prepare to open practice on Friday.

A highly rated recruiting class has boosted expectations for Georgia Tech, which finished only 12-19 last year.

The class includes three freshmen from the Atlanta area: forward Derrick Favors of South Atlanta High, point guard Mfon Udofia of Miller Grove High and guard Glen Rice Jr. of Walton High.

The 6-foot-10 Favors was named the nation’s top high school player by Parade magazine and was rated as the nation’s top prospect by some recruiting services.

Hewitt returns forwards Gani Lawal and Zach Peacock and guard Iman Shumpert as returning starters.

Another guard, senior D’Andre Bell, also returns after missing last season. Bell has been cleared to play after he was diagnosed last year with spinal stenosis, a congenital condition.

"Having D’Andre Bell back is as important as any addition we’ve had in the last year," Hewitt said.

Bell started 22 games in the 2007-08 season. He was regarded as the team’s best perimeter defensive player and had been named team captain last year before needing the season-ending surgery to correct the spinal condition.
