According to Jenna Laine of ESPN, the NFL will not allow the Bucs to fire off their cannons after scoring a touchdown, the team's traditional celebration. The NFL will permit the team to fire them off during the pregame player introductions, however.
The Bucs confirmed the report:
It makes sense. The Super Bowl is generally played at a neutral location, with this season being the first time in league history that a host city's team is playing in the big game. Allowing the Buccaneers to continue with their usual gameday traditions would eat away at the already thin veneer of this being played at a neutral site.
So no cannons for Tampa.
