Aberdeen boss Jimmy Thelin has confirmed extended lay-offs for injured duo Gavin Molloy and Ester Sokler.

Dons defender Molloy requires surgery on a shoulder injury sustained against Ross County on January 2 and is not expected to be back in action until May.

Striker Sokler is out for eight weeks with a hamstring injury picked up in the same game.

Ahead of the William Hill Premiership match against Hearts at Pittodrie on Sunday, where the Dons look to end their 10-game winless run, Thelin said: "It's clearly a big disappointment for us to lose both Gavin and Ester for extended time periods but our medical team will provide excellent guidance and rehabilitation for both players in the next few months to help get them back to fitness as soon as possible.

"We will continue to work to find solutions to help ensure the squad remains competitive and everyone at the club wishes them both a speedy recovery.
