The Legends of Pittsburgh Cruise turned into an unexpected opportunity for the Steelers' James Harrison, among others, to step into a hero role in the Gulf of Mexico on Saturday.

The veteran linebacker was among those Steel City celebs on a four-day jaunt through Miami, Key West and Cozumel when the ship spotted a home-made raft with 16 people aboard floating aimlessly in the middle of the body of water.

Harrison took to Instagram posting photos as the cruisers attempted to help the stranded 16 while awaiting help from the Coast Guard.
