Doncaster coach Tony Miller will be without dual-registered Hull FC centre Chris Green for Sunday’s Co-operative Championship One fixture with improving London Skolars.
Green is suffering from a hernia problem, but Leeds centre Mike Coady will continue to help fill the gap left by Green’s absence.
Doncaster are hoping to keep the pressure on the top five teams in the division, and a seventh win from 12 league fixtures would provide another welcome boost.
Dons director of rugby Carl Hall said: “Last we went to Gateshead and picked up the points, which is all you can ask for.
“When you play against a team who have had some big defeats, you are on a hiding to nothing as everyone expects you to win by at least 50 – but this is Rugby League, and the game throws some real challenges at you if you are not fully focused.”
London did not play last week, but Skolars director of rugby Mark Croston said: “The two week window gives us a good opportunity to get ourselves in top physical shape and prepare for the massive challenge facing us.
“We also have time to work on some weaker areas of our game – which will make us stronger when we face Doncaster.”
