John E. Moore III/Getty Images Colorado quarterback Shedeur Sanders signed one of the tortillas fans threw on the field during the Buffaloes' 41-27 win over Texas Tech on Saturday. Colorado Buffaloes Football @pchristy11 The tradition of tossing tortillas in Lubbock has reportedly been taking place since at least the 1980s. Per Brandi D. Addison of the Lubbock Avalanche-Journal, one explanation as to the origin of the tradition is that the tortillas were a replacement for soda lids that fans used to throw on the field. Another origin story is that the tossing was the response to a snub by an ESPN announcer, while another argues the tortillas were metaphorical food for the Red Raiders' previous nickname of the Matadors, per Addison. However the tradition started, the tortillas were in full flight ahead of Colorado and Texas Tech's kickoff at 4 p.m. ET on Saturday. Big Noon Kickoff
