But Rowley could make more changes after admitting every member of his squad is staking a claim for selection.
Rowley said: “We’ve got some middle-unit players ready and chomping at the bit, and it’s getting really difficult to not pick some players at the moment.
“We might just put some new bodies in this week, because the pressure from underneath is getting to the stage where I can’t ignore it.”
On Doncaster, he added: “They’re a big, physical side that’s full of confidence, so we’ll have to be tight in the middle and defensively honest.
“They’ve got two wins from three this year, and before that they had a Grand Final win.
“They’ve got team harmony, and all the consistent and winning teams in our leagues have shown that to be a factor in any success.”
Dons coach Tony Miller will check on Mark Castle (back spasms) before naming his squad.
Miller said: “Leigh will be a tough test for us, but there’s no pressure on our guys.”
He added: “Mentally we’ve come a long way. Our main focus this season was to consolidate and keep ourselves in this division, but if we can finish in the top eight then that would be as successful for us as last season.”
