Ralphie will not run today when the Colorado Buffaloes take on Stanford at Folsom Field at 1:10 p.m.

“The decision for her to run each game is made with the utmost of caution, with Ralphie’s well-being always being our number one priority, along with the safety of her handlers,” John Graves, Ralphie program manager, said in a statement from CU.  “Based on her temperament at her Friday practice last night, we just are not comfortable with Ralphie running today.”

CU said despite not running, Ralphie, who turned 13 in October, is in great health. She will still appear in her pen at Ralphie’s Corral for pregame festivities.

This is the second consecutive home game that Ralphie will not run.
