Colorado State will retire No. 14 across all sports in honor of Lt. Col. John Mosley, CSU’s first Black letterwinner, the school announced Thursday. The number will go up in Canvas Stadium on Sept. 7, and any athletes currently wearing No. 14 for the Rams will get to keep their number through the end of their eligibility. Mosley, a Denver Manual High School product, arrived in Fort Collins in the fall of 1939.
