Phelps was enlisted after players on the Ravens noted that they don't know how to swim to make full use of the team's new pool in their renovated athletic performance facility.

After taking a tour of the Ravens' new aquatic center and checking out practice with his 7-year-old son, Beckett, and franchise great Ray Lewis, Phelps got to watch some players take part in a diving contest and a swimming race, then it was time to get down to business.

Phelps also toured the smaller pools at the Ravens' facility, and he spoke to the team on the practice field along with former Ravens star Ray Lewis.
