Miami Dolphins' deal with Williams sisters announced

Serena and Venus Williams are the first female African-Americans to hold an ownership stake in an NFL franchise.

Their ownership stake with the Miami Dolphins was officially announced earlier today.

The sisters paid their first visit to the Dolphins' complex, watched some practice, checked out the weight room and chatted with several players.

At the press conference the sisters posed for photographers holding team jerseys — no. 11 for Venus and no. 89 for Serena (EleVen is Venus' clothing line; 8-9 is the birthdate of their half sister, Yetunde Price, who died in a 2003 shooting).
