George Boateng and Anthony Gardner are in line to feature for Hull at Newcastle this weekend.
The experienced duo missed the disappointing 5-0 hammering by Wigan on 30th August through injury, but have returned to training and are pushing for a place in Phil Brown's plans.
Boateng has been undergoing his rehabilitation from an ongoing thigh problem back in his native Holland, with a scan on Wednesday set to determine whether the midfielder is fit enough to face the Magpies on Saturday.
"George has been with a physiotherapist department that the national team of Holland uses over in Amsterdam," Brown told the Hull Daily Mail.
"He's been over there and come back looking in good shape.
"We'll get a further scan tomorrow and hopefully get the results of that on Thursday with a view to Saturday. It's touch and go, probably 50-50."
Gardner is currently recovering from minor surgery on a problematic thigh muscle, but Brown is adamant the defender will benefit from having gone under the knife.
"It's been an ongoing problem that he's had for probably the last two years and there was a lot of clotting and old blood in his thigh," added the Tigers boss.
"He's had the operation to remove all that and it must have taken three quarters of a pint of unwanted stuff out of his thigh muscle."
