The 20 year old currently has a 2 year deal with the Championship club but they are willing to let him go out and get some experience.
Speaking to the Star, boss Paul Warne said he would give Onariase a decision before the weekend.
“He’s done all right. He’s a good kid. He wants to improve. He’s pretty athletic, I’ve watched him today, we’ll watch him tomorrow and then we’ll make a decision on that. I don’t want to give the decision to the media before I give it to the lad. He’s had a really good week.” Warne said.
“He was happy to come in and prove his worth, When Richie picked him up and took him from the train station to the hotel, he knew all about me and Richie being players here together years ago. He’d researched the club, which is amazing. If it’s a tough decision, you have more chance of taking on someone with a general interest in the club than the other way round."
“He’s trained really well. It’s just whether I can give him some time on the pitch. We’ll discuss that with him and his agent and my coaches tomorrow.” he added.
