Forward Brandan Wilkinson has signed a new deal with Doncaster for the 2021 season.
The Scotland international has been with the club since the start of 2018. Wilkinson has played 24 times for the club so far, scoring three tries.
Chief executive Carl Hall said: “Brandan has been a good player for the club in the time he has been here so far.
“The key for him is to stay fit and healthy after a tough time with injury, he was ready to go in 2020 which means he has been keen to get going ever since.
“He is a player who adds a lot to our forward pack and is also clever with ball in hand so will add to the options we have next season.”
