Justin Fields is QB No.1 for now.

Chicago Bears coach Matt Nagy confirmed on Wednesday that the rookie pivot get his first career start at quarterback on Sunday against the Cleveland Browns.

"We're ready to attack this thing moving forward," Nagy said.

Fields, 22, entered last Sunday's 20-17 win over the Chicago Bears when Andy Dalton, who started the team's first two games, exited with a non-contact knee injury. The 33-year-old Dalton briefly returned, but left again and Fields played the entirety of the second half.

The 11th overall pick of the 2021 NFL Draft out of OSU, Fields threw for 60 yards on 6-for-13 passing with an interception. He also rushed for 31 yards on 10 carries.

On Tuesday, Nagy indicated that a healthy Dalton would still be the team's starter.
