A former Port Arthur Memorial football player was expelled from Baylor for a 2013 incident in which he and another player allegedly sexually assaulted another student, ESPN.com reported.

ESPN posted an online video for its investigative series “Outside the Lines” about Tre’von Armstead’s expulsion and the university’s handling of allegations of sexual assault by football players, which has come under much public scrutiny. Armstead, a fourth-year junior, was kicked off the Baylor football team on Sept. 18, 2015, for what the team described as an unspecified violation of team rules.

Two weeks earlier, according to an Associated Press story, Baylor defensive end Shawn Oakman and safety Orion Stewart were suspended for the SMU games for violating unspecified team rules. Oakman on Wednesday was arrested on charges he sexually assaulted a fellow student after leaving a Waco nightclub with her April 3, the Waco Tribune reported.

Oakman is Baylor’s all-time sack leader.

The date for Armstead’s expulsion from the university is not clear, but ESPN said an appeal of his expulsion was denied last week. ESPN reported Armstead’s family is considering a lawsuit against Baylor questioning the reliability of evidence it used to ban him from Baylor.

Outside linebacker Shamycheal “Myke” Chatman and Armstead were never formally charged, and both denied the assault occurred, ESPN reported. The network added Baylor took 2½ years to investigate when federal law requires colleges and universities to immediately report allegations of sexual abuse. The assault allegedly occurred during Diadeloso, or “The Day of the Bear,” a one-day break from classes in every spring that includes outdoor activities.

A police report, according to ESPN, cited that the woman who was allegedly assaulted was drinking and didn’t remember the assault. Friends said they heard the woman say, “no, no, please stop” and “a loud bang,” according to the report.

The woman reportedly went to police but declined to press charges. Baylor was contacted about the allegation, ESPN said citing the police report, although a Waco police spokesperson could not confirm who from the department contacted the university.

Armstead, 21, was a returning All-Big 12 tight end for the Bears before his dismissal from the team. He played in all 26 games as a redshirt freshman and sophomore. According to his Baylor player bio, he was rated the 10^th-best offensive lineman in Texas and No. 100 by Rivals.com’s Lone Star Recruiting Top 100.

He helped Memorial attain a 13-2 record and 6A state semifinal berth as a junior in 2011.
