Prince Buaben has signed a one-year contract with Hearts following a successful trial.
The Ghanaian midfielder was most recently on loan with Partick Thistle following spells with Watford and Carlisle after leaving Dundee United in 2011.
Head coach Robbie Neilson told Hearts News: "It's great that Prince has put pen to paper. He's been at training for the last two weeks and he's played a few games for us.

"He's looking good and he's a top player. He's played in the SPL for a long time and he's played in England at a very high level so I'm pleased to get him.
"He gives us a bit of strength in there. We've got some good options now in the middle of the field. He's a good character as well.
"He hadn't done a pre-season after he finished up last season so I just wanted to see where he was and he's a fit guy.
"If this is the condition he's in, having only trained for just over a week, then I'm looking forward to seeing what we can get out of him in two or three weeks' time."
