STEVE McClaren has thanked Republic of Ireland boss Martin O'Neill for playing a key part in helping skipper Richard Keogh be fit for Derby's County's clash against Reading.
Keogh suffered a hamstring strain while training with Ireland ahead of their Euro 2016 qualifier against Gibraltar last week.
He was ruled out of the game as well as the qualifier in Germany on Tuesday.
The central defender was released early from the national squad and sent back to Derby for treatment.
McClaren says O'Neill and the Republic of Ireland should take credit for their prompt action.
Keogh was able to train with the Rams squad yesterday as they prepare to face Reading in the Championship at the Madejski Stadium tomorrow (3pm).
"We thank Martin O'Neill and the Republic of Ireland for sending Richard back early and that has given us a chance to get him fit," said McClaren.
"Richard has trained and, hopefully, he will have no reaction to that, and be available."
Keogh has been ever-present this season in a defence that has kept four consecutive clean sheets.
He looks set to continue his centre-back partnership with Zak Whitbread, although Jake Buxton is fit again after missing the last five games due to a hip-flexor problem.
Buxton played an hour in a private friendly against Burnley at Moor Farm on Tuesday.
Ryan Shotton also adds to the competition for places at the heart of the back four.
"That is one of the things that has pleased me," said McClaren.
"When you lose somebody of the stature of Jake Buxton to injury, you wonder how you are going to replace him but not only has Zak come in but Ryan Shotton as well.
"It shows we have a strong squad and we will need that over the season."
Derby have also been boosted by Jordon Ibe's return to training.
The winger, on loan from Liverpool, has started the last four matches but struggled with a groin injury during the goalless draw against Millwall last time out.
The injury forced him to miss England Under-20s' successful participation in a Four Nation tournament during the international break.
"Jordon has trained this week and come through OK," said McClaren.
Simon Dawkins remains sidelined with a hip problem.
"He is getting closer," said McClaren. "He may start training next week with a view to being involved the following weekend."
Derby are unbeaten in 10 matches and have lost only once in 14 games this season.
