Gary Borrowdale looks set to return to QPR following the end of his month-long loan spell at Charlton.
The left-back has made six appearances since arriving at The Valley a month ago and the Addicks are keen to extend his stay. But Rangers boss Neil Warnock wants to run the rule over him.
"I've yet to have a look at Gary and I want to see him before the end of the season," said Warnock.
Borrowdale made the final appearance of his Addicks spell in Tuesday night's win over Colchester.
He could be back in the Rangers squad which hosts Cardiff on Saturday, although loanee Dusko Tosic is likely to stay at left-back following his successful debut at Crystal Palace last weekend.
