The report says that Walker and a friend, both underage, attempted to enter a bar and were turned away, thus resulting in the two assaulting security.
Walker was a 4-star prospect in the 2015 recruiting class, the highest ranked commit that Rich Rodriguez has landed throughout his five recruiting cycles in Tucson.
Walker was ranked 140th in the nation, and 10th among all tackles coming out of Chaparral High School in Scottsdale.
Walker tore his ACL in his senior year of high school and opted to grey shirt in order to recover while avoid burning any eligibility. He enrolled this spring and joined the team for practice.
Offensive line coach Jim Michalczik had high praise for his 6-foot-5, 283 pound tackle.
Walker is still on the team, and his punishment will be handled internally, according to a UA spokesman (via Zack Rosenblatt of the Arizona Daily Star).
