Williamson High assistant football coach Carl Jackson says that Coleman will make the announcement at Williamson, where he was a standout football and basketball player.
Coleman finished his redshirt junior season as an All-SEC defensive end. He earned his degree earlier this month, but has one more year of eligibility as a college player if he dedides to use it.
"I don't know what Antonio is going to announce and I don't think he has made a decision one way or the other," Jackson tells Inside the Auburn Tigers.
"Right now Antonio is weighing all of his options on what will be the best thing for him to do," the coach adds. "He wants to think about it carefully and make a good decision."
Despite playing with injuries much of the season, Coleman made 46 tackles with six quarterback sacks and 10 1/2 tackles for lost yardage. Coleman also was credited with 13 quarterback hurries for the Tigers.
Coleman made the coaches and Associated Press All-SEC teams this past season.
He started eight games and played in five others as a sophomore in 2007 and finished with 38 tackles with 8 1/2 sacks and 18 1/2 tackles for 84 yards in losses. In 2006 he played as a reserve in 13 games and made 18 total tackles with one stop for a loss.
