The Colorado football team has returned to the Top 25.
Following their 38-16 rout of UCLA on Friday, the Buffaloes landed at No. 21 in the Associated Press poll and at No. 22 in the Amway Coaches' Poll on Sunday.
This is the first time CU has been ranked since finishing the 2016 season at No. 17 in the AP and No. 15 in the Coaches poll. The Buffs were ranked nine weeks during the 2016 season. Prior to that, however, CU had not been in the top 25 since November of 2005.
CU (4-0, 1-0 Pac-12) enters this week as the only undefeated team in the Pac-12 and one of only 14 in the country. The Buffs are off to a 4-0 start for the first time since 1998, when they started 5-0 and finished at 8-4.
A week ago, CU was 26th in the AP voting, but teams ranked No. 20-25 went a combined 1-5 this past weekend.
Colorado will host Arizona State (3-2, 1-1) on Saturday at Folsom Field (2 p.m., Pac-12 Network). It will be just the fourth time in 13 seasons that CU will play at home as a Top 25 team.
