Desmond Ridder: Everything you need to know

Ridder (coach's decision) is inactive but will serve as the Packers' emergency third quarterback during Saturday's wild-card matchup versus the Bears, Mike Spofford of the team's official site reports. Ridder will serve as the team's No. 3 quarterback after being signed to the active roster from the practice squad earlier in the week. He is prohibited from playing unless both Jordan Love and Malik Willis were to exit the game due to injury, illness or ejection.

Green Bay signed Ridder off the practice squad Tuesday. Ridder replaces Clayton Tune as the Packers' QB3 behind Jordan Love and Malik Willis (shoulder) after Tune completed just six of 11 passes for 34 scoreless yards in Sunday's regular-season finale against Minnesota.

Ridder signed with the Packers' practice squad Wednesday, Tom Pelissero of NFL Network reports. Ridder spent last summer with the Bengals and then spent several weeks with the Vikings in two separate stints this season before being let go earlier this month. He'll operate as organization depth in Green Bay while Jordan Love (concussion) and Malik Willis (shoulder) work on getting healthy.
