Hearts have accepted a bid of around £1.5m for defender Lee Wallace from SPL champions Rangers.
The two clubs have come to an agreement after two initial bids from the Gers were turned down by Hearts.
While the Scottish side were hoping to keep the 23-year-old at Tyneside with a new deal, he is now likely to complete a switch to Ibrox, according to Sky Sports.
The Scotland international will be allowed to travel to Glasgow to undergo a medical and discuss personal terms.
