The dismissal came after a review of game tape of the Hokies' game against Louisville in the Gator Bowl on Monday, which showed Vick stomping the leg of Cardinals' defensive end Elvis Dumervil after a play in the second quarter.
In a statement Friday night, school president Charles Steger said a "cumulative effect of legal infractions and unsportsmanlike conduct" led to the action. That announcement came on the same day it was reported that Vick, a junior at Virginia Tech, had been ticketed for speeding and driving with a suspended license near his hometown of Newport News, Va., in December.
Steger said at a news conference on Saturday that he discussed the matter with both Vick's mother and Coach Frank Beamer.
"I'm very disappointed," Beamer said on the school's Web site. "I wish him the best."
