Rangers have no fresh injury concerns ahead of their visit to Perth.
Steven Gerrard 's side will travel to face St Johnstone on Wednesday night in a bid to keep an unbeaten Premiership season within their grips.
The champions have racked up 34 league games without defeat and an Invincible campaign is now a real possibility.
But they have a Scottish Cup quarter-final, also against Saints, to navigate this weekend and Gerrard could be tempted to make the odd change to the side which beat Celtic at the weekend.
James Tavernier may return to action after he took a place on the bench on Sunday following a knee problem.
The Rangers skipper could replace Nathan Patterson who, along with team-mates Bongani Zungu and Calvin Bassey, is waiting on news over the club's appeal against immediate four-match bans for breaching lockdown rules.
Leon Balogun has an achilles problem, Ryan Jack is out for the rest of the season and long-term absentee Nikola Katic remains on the sidelines.
On-loan Rangers winger Glenn Middleton misses out for St Johnstone and boss Callum Davidson reported a couple of injury doubts but did no elaborate on names.
Midfielder Murray Davidson is still working his way back from a calf injury which he picked up last time out against Rangers.
