A sheriff's deputy stopped Ebner at 1 a.m. Sunday after noticing an SUV swerving on a Columbia, Mo., street. An arrest report said Ebner had bloodshot eyes and incoherent speech and failed a breath-alcohol test.
Ebner, Missouri's third-leading tackler last season, was released from custody after posting a $500 bond. He faces a Sept. 16 court appearance.
A team spokesman said Monday any disciplinary action would be handled internally.
Ebner did not immediately return a phone call nor respond to an e-mail Monday. It wasn't clear if he had an attorney.
