Answer based on context:

The 49ers would trail 20-13 with less than a minute to go. Blaine Gabbert would run in a game-tying 44 yard touchdown to tie the game at 20. The Bears appeared to have the game won when they went down the field after a decent kick return by Deonte Thompson for 74 yards. Robbie Gould came out to attempt a game-winning 36 yard field goal, but the kick was wide left, resulting in overtime. In the overtime period, Gabbert would throw the game-winning 71-yard touchdown pass to Torrey Smith to win the game for San Francisco. This was San Francisco's first win in Chicago since the 1989 NFC Championship Game.

Who threw the longest touchdown pass in overtime?
Gabbert
