Quarterback Joe Flacco will sign with the Cleveland Browns and Zero AIjoin the team's practice squad, according to multiple reports.

ESPN was the first to report this development, which will add veteran depth behind rookie quarterback Dorian Thompson-Robinson and P.J. Walker following the Deshaun Watson's season-ending shoulder injury.

Flacco brings 15 seasons of NFL experience to the Browns, who are the fifth team for the quarterback.

Flacco was a first-round pick by the Baltimore Ravens in the 2008 NFL draft (18th overall) and helped the team win Super Bowl 47 during the 2012 season, earning Super Bowl MVP honors. Flacco, who played 11 seasons for the Ravens, is the team's all-time leading passing yardage leader with 38,245 yards (Lamar Jackson is second with 14,650). Flacco last played during the 2022 season, starting four games for the New York Jets.

In the wake of Watson's injury, Thompson-Robinson made his second career NFL start on Sunday in the Browns' 13-10 win over the Pittsburgh Steelers. Walker also made two starts earlier this season as Watson had been sidelined with a rotator cuff strain in his throwing shoulder.
