The Bengals boosted their offensive line when they signed Trent Brown, but the former New England Patriots tackle's season ended Saturday.
Cincinnati placed Brown on season-ending injured reserve after he suffered a brutal knee injury in the Bengals' loss to the Washington Commanders last Monday. The 10-year veteran's right leg was caught on the turf on pass protection, and he was carted off the field at Paycor Stadium.
Browns signed a one-year deal with Cincinnati last offseason after three seasons in New England where he won one Super Bowl.
The Bengals started the season 0-3 and faced an uphill battle without a top tackle protecting superstar Joe Burrow.
