Hearts have signed former St Mirren defender Mihai Popescu from Dinamo Bucharest on a two-year deal.
The Romanian, 27, spent six months with the Paisley side in season 2018-19, culminating in the Scottish Premiership play-off final win over Dundee United.
Popescu will be subject to a 14-day quarantine period after arriving.
"He's been training over the summer and we've sorted him out with gym equipment for his accommodation," said Hearts manager Robbie Nelson.
"I think he'll do well here. He can take the ball out from the back, which is key for us because we're expecting to have a lot of possession."
Hearts start their League Cup campaign against Inverness Caledonian Thistle on 6 October, and their League campaign just under two weeks later.
