New deal for Haley at Sale Sharks
The 22-year-old is a product of the Sale academy and his form last season saw him play for England Saxons in South Africa.
Since his debut against Saracens in 2013, Haley has established himself as Sale's first-choice fullback.
Mike has played 57 games for the club scoring ten tries.
"I'm delighted to sign a new deal at the club. It's a great environment and with the recent takeover of the club there is a good feeling around the club," Haley said.
"I am a Preston lad, played all my rugby in the North West, and want to help build the club and reach its full potential."
Club Director of Rugby Steve Diamond added: "Mike is one of the best fullbacks in the game and for him to sign a three year deal is great news for the club.
"He can go all the way to the top and it's a statement to clubs out there that we intend to keep hold of our home grown players as we aim to become one of the best clubs in Premiership."
