Dundee United target Aberdeen goalkeeper Danny Rogers

As their summer of signing continues, Dundee United could turn to Aberdeen goalkeeper Danny Rogers to help fill the gaps in their last line of defence.

With Deniz Mehmet out long term and Harry Lewis back at Southampton, the Tangerines are on the hunt for two first-team goalies.

And 24-year-old Rogers is one name on their list of possible additions.

New York born and an American citizen, Rogers was capped nine times at U/21 level for the Republic of Ireland, for whom he qualifies through his Irish mother.

He’s only played a handful of games for the Dons in six years at Pittodrie, but has over 100 top-team appearances under his belt during loan spells at Airdrie, Dumbarton and Falkirk.

Most of those games came during a two-year spell with Falkirk between 2015 and 2017.

He recently signed a two-year contract extension but could be available on loan again.

Deniz, meanwhile, is now likely to have the operation to repair knee ligament damage next week.

It was scheduled for early last week but the surgeon in England decided to delay it because the joint he damaged against Dunfermline in the play-offs last month remained swollen.

He’s likely to be out until around the turn of the year.

The Tangerines, meanwhile, have confirmed the signing of young Celtic defender Sam Wardrop and it’s understood Dunfermline’s Fraser Aird will be revealed as another member of the squad over the next few days.

A deal for Wardrop was agreed with the Hoops last week and the 20-year-old joins on a two-year contract.

The right-back has represented Scotland at U/15, U/16, U/17 and U/19 levels and captained Celtic’s Youth team to Scottish Cup victory in 2016.

“Sam is an athletic and energetic defender who likes to get forward and attack the opposition. I am pleased that we have secured his signing,” said boss Csaba Laszlo.

“We must build a squad capable of winning the Championship, and he will be an important part of the squad next season.”
