Philippe Clement has confirmed that Borna Barisic is missing from tonight's Rangers squad through injury.
The Croatian full-back has been a regular starter under the Belgian since he arrived in Glasgow, but he is absent against Hearts tonight due to a muscular strain.
"Yes, Borna has a slight muscle problem so he was not able to play this game. That's why he is not in the squad tonight."
Clement also spoke of his delight for Todd Cantwell who bounced back from his early substitution against Aris Limassol with a top display against St Mirren on Sunday.
The Ibrox boss said: "I was pleased for Todd like I am for every player.
"The most important thing is to win as a team. It is not about individuals.
"It is good of course that he played a good game after a game where he didn't show his qualities.
"That is important and I expect the same display again here against Hearts today."
