INDIANAPOLIS -- Jacoby Brissett will start in place of Scott Tolzien at quarterback for the Indianapolis Colts on Sunday against Arizona.
The move was officially announced a little more than an hour before kickoff.
He replaces Tolzien, who had two interceptions returned for touchdowns in last week's 46-9 loss. Indy also failed to convert a third down in the loss.
Andrew Luck still has not practiced since having surgery on his throwing shoulder in January.
Brissett was acquired in a Sept. 2 trade and has spent two weeks cramming to learn the playbook. He gave Indy (0-1) a spark in three series against the Los Angeles Rams.
Rookie cornerback Quincy Wilson and rookie safety Malik Hooker also will make their first career starts.
