TUSCALOOSA, Ala. -- Alabama fire officials say a blaze that gutted an NFL player's Tuscaloosa County home has been ruled arson.

Alabama State Fire Marshal Ed Paulk said in a release Friday that investigators have determined a late December blaze that destroyed the home of Dallas Cowboys linebacker Rolando McClain was set intentionally.

Details on what led investigators to that conclusion weren't immediately available. A phone message left with the state fire marshal's office wasn't immediately returned.

McClain's brick mansion was on the market for $1.5 million at the time of the fire. Authorities have said the fire at McClain's home was suspicious because the house was unoccupied and expensive. Authorities have also said a vehicle was seen speeding away from the scene.

Paulk says no arrests have been made.
