Ratliff was charged with suspicion of driving while intoxicated in Grapevine Jan. 22 after his pickup truck struck the back of a tractor-trailer rig. He was not injured.
In results released Monday, the Grapevine Police Department said Ratliff's blood-alcohol level was 0.16, "which is twice the legal limit," police spokesman Robert Eberling said in an email.
Officer Eric Barch, the first police officer to arrive at the accident scene, wrote in his report Ratliff did not initially appear to be intoxicated. The Dallas Morning News noted Monday Ratliff failed all three phases of the three-part Standardized Field Sobriety Test and was verbally abusive after he was jailed.
The arrest came six weeks after Ratliff and his teammates attended the funeral of Jerry Brown, a Cowboys player killed when a car driven by teammate Josh Brent crashed in Irving, Texas. Brent has been indicted on a charge of intoxicated manslaughter.
