For the 2018 regular season, he served as the backup to Mitchell Trubisky. In week four, he saw action against the Tampa Bay Buccaneers on a trick play nicknamed "Willy Wonka", which had been designed by coach Matt Nagy and the quarterbacks and named by Daniel days before the game. On the Buccaneers' three-yard line, Daniel joined Trubisky in the backfield in the shotgun formation. Before the play began, receiver Taylor Gabriel and tight end Trey Burton moved along the line of scrimmage to confuse the defense. Upon receiving the snap, Trubisky quickly pitched the ball forward to Gabriel on a shovel pass. Trubisky then faked a hand-off to Daniel as Gabriel scored the touchdown.
