The senior intercepted two passes in a 10-5 win against Stanford on Saturday. His second pick set up a key field goal for the Buffs in the closing minutes.
Thompson added five tackles, a third-down stop and a touchdown saving play for the 23rd-ranked Buffs (6-2, 4-1 Pac-12), who achieved bowl eligibility for the first time in nine seasons.
This is the fifth time this season that the Buffs have earned a conference player of the week honor, their highest single-season total since winning five in 2004. The Buffs had just six player of the week honors in the previous five seasons combined.
Other Buffs to be honored this season: quarterback Sefo Liufau (Sept. 5), quarterback Steven Montez (Sept. 26), kicker Davis Price (Oct. 3) and running back Phillip Lindsay (Oct. 17).
Thompson now has four interceptions this season and 10 for his career. He's just the 13th player in program history with 10 or more interceptions. During the last 20 years, the only CU player with more interceptions was Terrence Wheatley, who had 14 from 2003-07.
