FAYETTEVILLE, Ark. -

Police say University of Arkansas quarterback Brandon Allen's truck was one of three involved in a pair of vehicle fires early Monday.   They say it's too early to say if the fire was related to Allen's position on the football team.

Sgt. Craig Stout said the police and fire departments responded to a call at 3:59 a.m. and discovered Allen's Chevy Avalanche — which is registered to his father and former Arkansas assistant coach Bobby Allen — on fire. Stout says the car fire was the second of the morning, following a call approximately two hours earlier a few miles away from Allen's truck.

Stout says investigators are working to determine the cause of the fires.

Allen's truck was egged following a loss to Mississippi State last season.
