In a social media video, Ravens Marlon Humphrey, Ronnie Stanley, Kyle Hamilton and Charlie Kolar invited Phelps, a Baltimore native and longtime Ravens fan, to visit their training camp. They said that one in three Ravens players could not swim.

Michael Phelps is a man of his word. The Baltimore Ravens successfully enlisted the 23-time Olympic gold medalist to teach them how to swim. Phelps recently followed through with that promise to the benefit of Ravens ' defensive tight end Travis Jones.
