Paul Cooke is convinced his newest recruit Mitch Clark will prove to be a more than adequate replacement for Mark Castle.
Clark joined Doncaster from NRL side Penrith Panthers last week, subject to international clearance.
The 21-year-old, who has been training with the Dons for three weeks, can play across the pack but is expected to be utilised in the front row.
“He is solid in the middle, he has a good pedigree coming from Penrith and hopefully this will allay fans fears that we haven’t replaced Mark Castle,” said Cooke.
“He has fitted in really well here.
“We’ve still got some red tape to get through but Mitch was born in England so we don’t envisage too many problems.
“He is a great lad, he is well mannered and respectful, he has come over from the other side of the world so it is a big step for him.
“Mitch has a good engine, he is strong in the tackle with a lot of impact both in attack and defence.
“It is a really good addition for the club at his age and it brings the average age of the squad down.”
Chief executive Carl Hall added: “We are very happy that Mitch has agreed to join us subject to clearance.
“There was a lot of competition for his signature, however my relationship with his father Trevor, having played with him at Bradford, was a key factor in bringing Mitch to the club.
“He has a lot of potential and we hope we are able to get the best out of him here at Doncaster.”
