The Pittsburgh Steelers have signed free-agent quarterback Mitchell Trubisky, according to the NFL.

NFL Network's Mike Garafolo reported that the Steelers agreed to a two-year deal with Trubisky, citing informed sources.

The former No. 2 overall pick of the Chicago Bears is expected to be the starter over Mason Rudolph and former first-round pick Dwayne Haskins, according to Garafolo.

Trubisky spent his first four seasons in Chicago and made the Pro Bowl in his second season, but struggled afterward and fell out of favor with Bears fans. He spent 2021 in Buffalo rehabbing his image, but made only eight pass attempts as Josh Allen's backup.

In his last season as a starter, Trubisky completed 67% of his passes for 205.5 pass yards, 16 passing touchdowns, eight interceptions, and 93.5 passer rating -- nine starts in 2020.

The team hasn’t announced the acquisition.
