Answer based on context:

Tampa Bay won their first game of the season, as well as the first win for new head coach Lovie Smith. One week after a humiliating loss at Atlanta, the Buccaneers bounced back, and upset the Steelers, the first win in franchise history at Pittsburgh. Trailing 24-20 just inside the two-minute warning, Tampa Bay drove to the Pittsburgh 14 yard line. The Steelers forced a turnover on downs, and took over at their own 14. The Tampa Bay defense held the Steelers to a 3 and out, and forced a punt with 50 seconds left in regulation. Brad Wing's punt was high and short, and was downed inside Pittsburgh territory on the 46. Two plays later Mike Glennon, connected to Louis Murphy, who broke free for a 41-yard gain all the way to the 5 yard line. With 7 seconds left, Glennon completed the game-winning touchdown pass to Vincent Jackson in the left corner of the endzone.

Who threw the last touchdown pass of the game?
Glennon
