A Washington State freshman football player was released from Whitman County jail Friday morning after being held on a second-degree assault charge resulting from an alleged punch that broke a teammate’s jaw.

Emmitt Su’a-Kalio, a 6-4, 245-pound defensive end who hasn’t played and likely will redshirt this season, was brought to the WSU campus police Thursday by a member of the coaching staff after the victim called police to report a Tuesday-morning incident, said Steve Hansen, assistant police chief.

“It sounds like he was sucker-punched; he didn’t even see it coming,” said Hansen. He said department policy is not to release victims’ names.

WSU spokesman Bill Stevens said Friday evening the incident is being treated as a “team matter,” and declined to offer more details.

Hansen said the second-degree charge requires a significant injury. He said Su’a-Kalio, from Pago Pago, American Samoa, declined to offer details of the incident. The Spokane Spokesman-Review said Su’a-Kalio appeared in Whitman County court Friday afternoon.
