As revealed by HITC Sport last weekend Queens Park Rangers had a bid accepted by Huddersfield for Smithies as they look to bolster their goalkeeping options.
QPR are in the market for a new goalkeeper after seeing Alex McCarthy leave for Crystal Palace, while Rob Green has been linked with a possible move back to West Ham.
Chris Ramsey has been linked with a number of 'keepers, but it appears he has identified Smithies as the man he wants to bring in.
Smithies was involved in Huddersfield's opening day defeat at Hull but has not featured in either of their last two games, with Joe Murphy starting in goal due to the speculation over his future.
The 25-year-old is now undergoing a medical at QPR and if he comes through that he is set to become the club's latest signing this summer.
Smithies has made over 250 first-team appearances for Huddersfield since progressing through the club's academy to make his debut as a 17-year-old in December 2007.
