Commenting the latest acquisition Forward Coach Glen Kenworthy said. “I’m delighted that we have brought Tom on board and I’m looking forward to working with him next season.
“He’s been a rock over at Rotherham during a really tough period and will bring some fantastic leadership qualities to the group.
“He’s the type of player you really don’t want to play against and is a nuisance for opposition.
“We first came across Tom at Nottingham, he is seasoned campaigner at this level despite still being quite young and will add more competition to an already very competitive pack.”
Speaking on the move, Tom added. "I am very pleased to have committed myself to Doncaster for the next two seasons, they are a great club and have been a force to be reckoned with in the Championship for the last few years.
“Having spoken to Griff and a couple of ex-Rotherham players that have made the move to Doncaster I am excited about signing and feel I would fit into what is already a strong and experienced pack."
