*TCU will face Oregon in the Alamo Bowl on Saturday, but their starting quarterback will Trevone Boykin will not be on the field.

The athlete was arrested and charged with a third-degree felony in San Antonio early Thursday after fighting at a bar and then allegedly striking a bicycle patrol officer.

Formally charged with assaulting a public servant, Boykin posted a $5,000 bond and was released from custody late Thursday morning, according to ESPN.

A source told ESPN’s Jake Trotter that Boykin was in his room when his coaches did curfew check at midnight, but then he slipped back out and went three blocks to a spot called Pat O’Brien’s.

TCU coach Gary Patterson issued a statement saying: “Trevone Boykin and [junior wide receiver] Preston Miller have been suspended for Saturday’s game due to a violation of team rules. We are disappointed in their actions and apologize to the TCU Horned Frogs Nation, Valero Alamo Bowl and city of San Antonio.”

Senior Bram Kohlhausen or redshirt freshman Foster Sawyer will start in Boykin’s place.

At a Thursday morning news conference, San Antonio Police chief William McManus confirmed reports that Boykin, 22, and some teammates were at Pat O’Brien’s just before 2 a.m. when some patrons recognized the quarterback and began to trash-talk. Boykin became upset and a scuffle ensued. In the melee, Boykin struck a bar employee.

Boykin and the people with him were removed from the bar, but the fight continued. San Antonio bicycle police officers arrived at the scene and tried to stop the fight with the help of bar bouncers. According to an incident report provided by the San Antonio PD, the suspect “was very aggressive and was being held back by the group that he was with. Members of his group stated they would get him back to the hotel they were staying at.”

After walking away, the suspect, whom police were told by bystanders was Boykin, charged officers. McManus said that he was swinging and struck an officer in the face. Several officers then took Boykin to the ground. After officers threatened to use a stun gun on Boykin, he was arrested. In addition to the charge of assaulting a police officer, he also faces charges of resisting arrest and public intoxication, according to the police chief.

“We don’t know if he was swinging at the officer or somebody behind him,” McManus said. “In any event, the officer was struck in the face and suffered injuries.”

“Clearly this was not an appropriate way to act,” McManus said of Boykin. “He was heckled and he responded to it.”

A manager at Pat O’Brien’s told ESPN’s Max Olson that security footage already has been turned over to police.

Boykin is a senior who passed for 3,575 yards with 31 touchdowns and 10 interceptions this season. The Dallas native was a second-team All-American last season and a preseason candidate for the Heisman Trophy this year.
