Doncaster have confirmed that prop Kyle Sampson has left the club.
Sampson, 22, made 15 appearances for the club last season but has struggled to force his way in to the first team this season.
Dons head coach Tony Miller said: “We’re sorry to see Kyle go and it’s disappointing that he didn’t want to stay and fight for his place.
“We wish him all the best for the future.”
Sampson, who joined the club at the start of 2011, is a graduate of the Leeds Rhinos academy.
