The Derry native notched his first goal in the Championship in a comprehensive victory and his performances have drawn praise
O'Kane, 23, netted the third goal of the game - and his first goal in the Championship - with a solo effort and team mate Shaun MacDonald believes that the Republic of Ireland youth international is "going from strength to strength."
"Eunan came in for me and I think he has been brilliant," MacDonald told the club's official website.
"He got a goal and he looks like he is going from strength to strength, which can only be good for the team.
"He's a clever lad and an intelligent footballer, and he has played really well since he has started playing in that role.
"But he's also shown other sides of his game; running with the ball and driving at people is one of his strengths and you could see that when he scored his goal."
Elsewhere, Andy Reid took his goal tally in the Championship this season to seven goals in Nottingham Forest's 2-0 win over Queens Park Rangers at the City Ground.
However, the Republic of Ireland international's goal sparked controversy as the assistant referee had initially raised the flag for offside before lowering it, allowing Reid to score.
"I just saw the linesman put his flag up," said QPR boss Harry Redknapp after the game. "Then I turned around to speak to Joe Jordan and didn't see what happened after that.
"But at the end of the day, when you first start playing football from six years of age, the first thing you learn is to play to the whistle.
"If the referee doesn't blow the whistle, then you've got to play on. Forest did."
