Alex Smith continues his impressive comeback.

Since being named the starting quarterback, Smith has led Washington to a 3-1 record, the latest victory coming against the undefeated Pittsburgh Steelers.

The former Utah quarterback threw for 296 yards and a touchdown in Washington’s 23-17 win over Pittsburgh.

Down 17-10 early in the fourth quarter, Smith engineered an eight-play, 53-yard touchdown drive, that culminated in a 15-yard game-tying touchdown pass to Logan Thomas.

Alex Smith overcame the impossible in returning to the NFL. Now he has Washington back in playoff hunt

After Washington’s defense got a stop, Smith and the offense took the field again with five minutes remaining. This time, Smith drove Washington 45 yards down the field for the game-winning field goal. Smith had the play of the drive, connecting with Cam Sim — Sims made a great one-handed grab — on 3rd-and-4 to keep the drive alive.

With the win, Washington is now tied with the New York Giants atop the NFC East, with four games remaining.

It’s another chapter in Alex Smith’s incredible comeback story, which saw him go from being septic and possibly having his leg amputated to quarterbacking a team in a playoff race in just two years.
