Weiss was put on a bus to Roanoke, Va. -- an 833-mile trip, one way -- after he was not present for a 1 a.m. bed check early Thursday, Virginia Tech spokesman Bryan Johnston said.
Weiss, a fifth-year senior, was elevated from a backup role when kicker Cody Journell was suspended last week after being arrested for his alleged involvement in a home invasion.
Weiss missed his only field goal try this season, a 29-yard attempt.
Virginia Tech (No. 11 BCS, No. 17 AP) now has one kicker with experience -- kickoff specialist Justin Myer, who missed both of his field goal tries -- from 57 and 53 yards -- this season.
Myer is expected to handle the place-kicking against No. 13 Michigan, Virginia Tech coach Frank Beamer told reporters Thursday. But he said punter Michael Branthover and redshirt freshman Conor Goulding both would get a crack at the job in practice.
"We had curfew. We talked about it a lot. (Weiss) didn't make it and we're going to send him home," Beamer told reporters of the decision.
"My kickers are not bad guys," Beamer added. "They just made bad decisions. And young people do that."
