MIAMI GARDENS, Fla., Aug. 4 (UPI) -- The Miami Dolphins continued their off-season restructuring, with CEO Tom Garfinkel relinquishing several front office roles, the team announced Tuesday.

Dolphins owner Stephen Ross also announced Tuesday that son-in-law Daniel Sillman was named CEO of Ross Sports & Entertainment, which he recently formed.

That entity, also known as RSE, will include the Dolphins, Hard Rock Stadium, the Miami Grand Prix, the Miami Open tennis tournament and the Precision Drive Club.
