The Colorado football team has lost a pair of graduate assistants.
Offensive grad assistant Patrick Williams and defensive grad assistant Tyrone McKenzie have left the Buffaloes for other opportunities.
CU associate athletic director David Plati said Williams will work with the NFL's Baltimore Ravens, while McKenzie will join the staff at Stanford. It's not clear what role either will fill with their new teams.
Both were valuable members of CU's staff during their time in Boulder.
Williams, a former CU receiver, returned to the Buffs in 2013 as the assistant director of recruiting.
