J.T. Shrout will start at quarterback for Colorado on Saturday when the Buffaloes play at Air Force Academy, multiple outlets reported.
Colorado coach Karl Dorrell did not announce a starter this week.
In a season-opening 38-13 loss to TCU, Colorado started Brendon Lewis, who completed 13 of 18 passes for 78 yards.
Shrout, a transfer from Tennessee, made his Colorado debut in the second half. He was 13-of-23 passing for 157 yards and a touchdown.
Last season, Lewis started all 12 games as a redshirt freshman. He finished the season 149-of-257 passing for 1,540 yards and 10 touchdowns with three interceptions as the Buffaloes posted a 4-8 record (3-6 Pac-12).
Colorado will play at Air Force Academy for the first time since 1974.
