Manziel was seen on the sidelines before the TCU-Texas Tech game at Amon G. Carter Stadium. Manziel played under Tech coach Kliff Kingsbury when both were at Texas A&M for his Heisman-winning season in 2012.
Kingsbury was the Aggies’ offensive coordinator for Manziel’s sensational season, and was then hired by Tech.
Manziel was a first-round draft pick by the Cleveland Browns, but had a short, polarizing NFL career. He is trying to resurrect his playing career in the Canadian Football League with the Montreal Alouettes.
