"We are delighted that Jordan has accepted the offer of a new contract," said head coach Marcelo Loffreda. "He is in a very competitive Leicester Tigers squad and he has enjoyed good form this season.
"He is one of a number of impressive young English forwards in the Leicester squad and has earned his place in the England Saxons squad for their forthcoming internationals."
Crane said: "I've been pleased with the way things have been going and with the progress I've made this season.
"It was a great option for me to stay longer at Leicester. With the quality of the players and the club, it was a bit of a no-brainer really. I wouldn't have signed if I didn't think the club has a bright future."
