MIAMI (AP) — Venus and Serena Williams have found a new sport: pro football.

The tennis-playing sisters will become the latest celebrities to own a stake in the Miami Dolphins, a person familiar with the deal said Wednesday. The person didn't want to be identified because the team plans an announcement Tuesday.

Another person close to the negotiations said an agreement was near but not yet final. That person also didn't want to be identified because the announcement has not been made.

"There have been preliminary talks, and hopefully it'll work out," Serena Williams said Wednesday night after a 6-3, 6-2 win over Yaroslava Shvedova in Toronto. "That would be a great opportunity for both of us. You never know."

The Williamses live in Palm Beach Gardens, Fla., about an hour's drive from the Dolphins' stadium. Their new role will be significant in part because the NFL has no African-American majority team owner.
