Bruce admits he's been keen to take a closer look at both youngsters.
"The two lads on loan, in particular, I was going to have another look at in pre-season," Bruce told NUFC TV.
"We don't even know when the next pre-season is going to be so I think it's an ideal time to bring them into the squad.
"I've never seen Barlaser play - he's had good reports down in Rotherham - so let's give him the opportunity to come and train with the players and be a part of us going forward.
"It's a good chance to have a look at them. That's what we're doing as far as them two are concerned. As I've said, they've both had successful loan spells out so let's bring them in, have a look and see where they're up to."
