The Miami Dolphins are making way for the biggest names in tennis now that the Miami Open is underway at Hard Rock Stadium.
Superstars Serena Williams, Roger Federer, and Novak Djokovic took part in a ribbon cutting at center court on Wednesday.
The main stadium has room for 14,000 fans and 29 other courts are spread out around the stadium.
The Miami Open moved from Key Biscayne after years of conflict and growing pains.
Serena Williams says "only Miami" could transform an NFL stadium into a tennis venue and Roger Federer said he's excited to play in front of big crowds.
Federer says tennis is not known as an innovative sport, but he applauds the move calling it a "big, massive moment for our sport."
The tournament runs through March 31st.
