INDIANAPOLIS (AP) — When the Indianapolis Colts needed Joe Flacco to relieve the injured Anthony Richardson, the 17-year veteran kept it simple.

The 39-year-old Flacco threw two touchdown passes, and the Colts got the stop they needed in the final minute to preserve a 27-24 victory over the previously unbeaten Pittsburgh Steelers on Sunday.

“You just see the guy and hit him. That’s all you do,” Flacco said after going 16 of 26 for 168 yards. “Some guys like to think about every little thing and that’s how they play best. But I think my personality lends itself to this kind of situation. Just don’t overthink it.”

The one-time Super Bowl MVP and a longtime Steelers nemesis during his 11 seasons with Baltimore proved he could still play at a high level last season when he helped the Cleveland Browns reach the playoffs. Indy signed Flacco as a free agent to back up the injury-prone Richardson.

Richardson left twice in a span of four plays, initially taking a big hit on his right hip and later after a hard hit to the head, both on designed runs. He went straight to the locker room the second time and was ruled out by the time he returned to the sideline.

Coach Shane Steichen had no immediate update on Richardson or running back Jonathan Taylor, who hurt an ankle in the final minutes.
