A Dallas Cowboys player was arrested on suspicion of intoxicated driving in Grapevine, Texas, on Monday night.
Defense lineman Jay Ratliff was arrested after he collided with an 18-wheeler.
A Grapevine police officer told NBC 5 DFW that Ratliff did not even realize he had caused a wreck when officers questioned him at the crash scene.
"He had no idea how the crash occurred, and so I would just leave it at that," Senior Police Officer Sam Shemwell said.
Shemwell said Ratliff knew he had been involved in a crash but didn't know what had caused it.
Police said Ratliff refused sobriety tests at the scene and was arrested. Police obtained a search warrant, and he was taken to a hospital for a mandatory blood draw.
The results of the test are pending.
Ratliff was released on $500 bail on Tuesday morning.
The driver of the 18-wheeler was not injured, Grapevine police said. Ratliff, who was driving a Ford pickup truck, complained of minor injuries but refused medical treatment, police said.
The Dallas Cowboys declined to comment on Ratliff's arrest.
Ratliff is the second Cowboy to be arrested in a drunken-driving crash since December. Josh Brent, who replaced Ratliff on the field because of an injury, was arrested Dec. 8 on suspicion of intoxication manslaughter in a one-car crash that killed Cowboys practice-squad member Jerry Brown Jr. He was indicted later last month.
