Villa suspend Bannan after motorway crash
Bannan, 21, was arrested by police on suspicion of drink driving - along with Shrewsbury Town striker James Collins, a former Villa player - and was subsequently bailed.
Villa boss Alex McLeish, said in a statement issued to the media: "Barry Bannan has been suspended while the club carries out internal enquiries into allegations which arose last weekend.
"He will not be available for this weekend's game at Sunderland."
Bannan, who has played nine times for Scotland, was involved in the accident on the M1 motorway at around 04:30 GMT on Sunday morning.
