Ga. Tech RB Orwin Smith doubtful

CHARLOTTE, N.C. -- Georgia Tech leading rusher Orwin Smith did not practice on Thursday because of a right ankle injury and is listed as doubtful for Saturday's Dr Pepper ACC championship game against Florida State, according to a school spokesman.

Smith has rushed for 673 yards and five touchdowns this season. He is averaging 9 yards per carry and also has 14 kickoff returns for 267 yards.

Smith injured his right ankle in a Nov. 17 win over Duke and missed last week's game against Georgia. On Monday, Smith said he expected to play.

The Yellow Jackets could turn to a running-back-by-committee approach should they need to replace him. The most likely candidates are B.J. Bostic, who started in Smith's place last week against Georgia, and Synjyn Days, who started the second half last week.

Tony Zenon (25 carries, 191 yards and a touchdown) and Deon Hill (five carries, 42 yards) also likely will play.
