Baylor offensive coordinator Kendal Briles and receivers coach Tate Wallis will miss the fourth-ranked Bears' game Saturday against Lamar because of self-imposed NCAA penalties, according to a person familiar with the matter.

NCAA investigators interviewed high school coaches in the Dallas-area in May after Briles and Wallis were accused of impermissible contact with recruits at spring games and a track meet, according to the source.

Under NCAA rules, coaches are not allowed to have off-campus contact with recruits during the spring evaluation period.

Baylor athletic director Ian McCaw declined to comment.

​Briles is the son of Baylor coach Art Briles and is in his first season as the Bears' offensive coordinator after previously serving as an assistant for seven years. He was investigated by the NCAA in 2014 for impermissible contact with recruits but later cleared.

Wallis is a first-year Baylor assistant. He worked in off-field roles for the Bears for the previous five seasons.

Art Briles has been under fire in recent weeks after former Bears defensive end Sam Ukwuachu was convicted last month of sexually assaulting an ex-Baylor soccer player in 2013.

Briles has maintained he did not know of Ukwuachu’s violent past at Boise State before accepting him as a transfer in 2013. Former Boise State coach Chris Peterson, now Washington’s coach, said in a statement that he called Briles and “thoroughly apprised” him of the circumstances surrounding Ukwuachu’s disciplinary record and dismissal.

Baylor has launched an internal inquiry into the matter. The Bears won their season-opener last Saturday against SMU 56–21. Defensive end Shawn Oakman and safety Orion Stewart missed the game for a violation of team rules.
