The ex-girlfriend of University of Colorado assistant coach Joe Tumpkin has obtained a restraining order against Tumpkin, claiming he physically assaulted her multiple times over the course of their three-year relationship — most recently on the nights before and after a CU football game.
Tumpkin, 45, has been the safeties coach at CU for the past two years.
He assumed defensive play-calling duties in the Buffs' bowl game last month after defensive coordinator Jim Leavitt left for a job at Oregon, and is one of the candidates to replace Leavitt.
