It's Trubisky time in Chicago.

The Bears have made a change at quarterback, benching the underperforming Mike Glennon in favor of rookie Mitchell Trubisky for their Week 5 contest against the Minnesota Vikings.

It will be the first career start for the No. 2 overall pick in this year's draft.

Trubisky had impressed in the preseason, completing 67 percent of his passes for 364 yards and three touchdowns, but took a backseat to Glennon when the regular season began. The Bears targeted Glennon in free agency to be their starter for the 2017 campaign, but he's committed eight turnovers in the first four games.

The Bears were embarrassed 35-14 by the Green Bay Packers on Thursday night as Glennon threw two interceptions and lost two fumbles.

With 10 days between games, the Bears are afforded extra time to prepare Trubisky for the Monday night matchup with the Vikings.

While Minnesota boasts the superior defense, the Vikings may be without starting quarterback Sam Bradford once again, while rookie running back Dalvin Cook suffered a knee injury Sunday and is out for the season.

The Bears will play the Baltimore Ravens, Carolina Panthers, and New Orleans Saints in subsequent weeks before their bye.

The only other rookie quarterbacks that have seen the field this season are No. 12 overall pick Deshaun Watson of the Houston Texans and the Cleveland Browns' second-round pick, DeShone Kizer. Kizer has started every game this season in Cleveland, while Watson has electrified the Texans' offense, accounting for five touchdowns in a 57-14 blowout win over the Tennessee Titans on Sunday.
