Jamie Walker has joined Bradford City on loan.
The midfielder makes the move to Valley Parade until the end of the season.
Speaking to the Official Hearts Website, manager Robbie Neilson said: “The move comes down to the fact that Jamie wants to play more games.
“We have a really strong squad and competition for places is fierce, so there are no guarantees that anyone will be an automatic starter.
“There is no doubting Jamie’s talent and whilst I would have been delighted to have him here with us for the second half the season, we must respect his decision and desire to play regular first team football.
“Jamie goes to Bradford with our best wishes and the group now returns to training as we prepare to build upon what has been a fantastic first part of the campaign.”
