Riether undecided over future
Gary Naysmith and Ryan Jack will both be added to the squad for Aberdeen's Clydesdale Bank Premier League game against Dundee on Friday night.
Naysmith (hamstring and calf) and Jack (broken foot) are both in contention for the clash at Pittodrie after recovering from their respective injuries.
Boss Craig Brown has no fresh injury worries but will be without the suspended Mark Reynolds.
Dundee manager Barry Smith has two unnamed doubts for the game, while striker Steven Milne is battling to overcome a rib injury.
Dundee are still without long-term injured players Stephen O'Donnell (knee), Mark Kerr (knee), Davide Grassi (knee), Jamie McCluskey (Achilles) and Carl Finnigan (knee).
The 43-year-old had transformed the Sky Blues' season after being installed as Andy Thorn's successor in September, steering them from a potential relegation battle in League One to the fringes of the play-offs.
But the Terriers, who sacked Simon Grayson three weeks ago after going 12 games without a win, were granted permission to approach Robins on Tuesday after Coventry had rejected an initial approach.
Nigel Adkins, sacked by Southampton last month, had been installed as the early favourite to replace Grayson, but Huddersfield maintained Robins had been their first choice and he was unveiled on Thursday as the club's fifth manager in as many years at their Canalside training headquarters.
"It was a considered decision," said Robins, who alluded to the current rent dispute between the club, Arena Coventry Ltd - the owners of the Ricoh Arena - and Coventry City Council.
"I spoke to the owner, I sought assurances and didn't get any assurances from the owner of Coventry," he said.
"I absolutely wish them all the best, they work their socks off and as I've said before that club needs support from Coventry City Council.
"That led to a decision to want to speak with Huddersfield and that's how the decision has been arrived at."
Riether, 29, is currently on loan from German club Cologne but has impressed for Fulham since joining in the summer.
The former Wolfsburg full-back has already featured 29 times for Martin Jol's side, but could still be plying his trade back in Germany next campaign.
"Nothing is decided yet," he told German magazine Kicker. "Fulham can activate a clause, and I also have to agree.
"As things stand now, I will return to Cologne in the summer. But I have to consider and talk to both clubs.
"I wanted to become a starter (at Fulham), and I managed to do that. I am proud I have become a fans' favourite. But of course I can still do better, and that's what I am trying to do."
Riether was also full of praise for his fellow Barclays Premier League players and believes the style of football in England compliments his own abilities more than in his native country.
"The players here all have an amazing individual quality," he said.
"Even smaller clubs take on high-profile players for a lot of money - there are also fewer dives here.
"The football here suits me. Moreover, the club is very friendly and I received a warm welcome."
Riether has made the right-back position his own since moving to Fulham, with the likes of Stephen Kelly moving away from the club due to Jol's preference for the on-loan German.
Despite his current status at Craven Cottage, Riether admits it did take him time to settle and tackle the language barrier.
"It wasn't easy with the language," he said. "At first, I got nothing of what our Scottish assistant coach [Billy McKinlay] said, and the football is different."
