An Auburn official told Inside the Auburn Tigers on Monday that the Smith's dismissal was the result of violation of team rules.
That leaves the Tigers with two or three scholarship running backs heading into spring training, which is scheduled to start on March 23rd. Onterio McCalebb and Michael Dyer return at tailback while redshirt freshman Ladarious Phillips could play fullback or may line up at defensive tackle.
Smith started 12 games and played in 36 games the past three seasons for the Tigers. He rushed for 182 yards and one touchdown on 42 carries. He caught 25 passes for 278 yards and one touchdown.
In August of 2009, prior to his sophomore season, the running back from Armwood High in Seffner, Fla., was arrested on a charge of disorderly conduct at the Lexington Inn on South College Street.
This past season Smith carried the football just one time in 14 games for no gain. He caught five passes for 49 yards. On special teams he made three solo tackles with two assists.
Seven of Smith's starts came in 2010 when he rushed for 99 yards on 20 carries and caught 18 passes for 226 yards.
He has a younger brother, Petey, who is a linebacker for the University of Alabama.
