Thomas, a sophomore, missed the team's season opener against Oklahoma State with an ankle injury and was suspended indefinitely on Sept. 5 for an undisclosed violation of team rules. He was a five-star recruit in the class of 2013.
Fisher said Thomas will have to earn playing time:
"He is a great athlete, but we have some other great players. It is not like he walks in and changes everything," Fisher said last week. "He is a tremendous special teams guy because he has range and size, hard to block and can cover. He can rush off the edge and he can blitz the middle and he can play middle backer. He brings a lot. He has good ball skills."
He appeared in four games as a true freshman last season for the Seminoles, recording four tackles and one sack.
The No. 2 Seminoles are 6-0 and have won 22 straight games. They host No. 5 Notre Dame on Saturday at 8 p.m. ET on Saturday.
