Steven Reid has returned to his role as first-team coach at Nottingham Forest.
The former Ireland midfielder had previously held the position under Chris Hughton - and was temporarily placed in charge when Hughton departed in September 2021.
He left the club last summer and began working in the field of mental health.
Commenting on his return, Reid said: “I am absolutely delighted to return to Nottingham Forest.
“It is a club that has stayed close to my heart for many reasons, firstly because of the amazing journey to promotion, but also because of the support I felt from within the club and the amazing fanbase when stepping away from football to do some work around mental health and well-being.
“I have remained close to Steve and many of the coaching staff and players and cannot wait to get going again.”
Forest boss Steve Cooper added: “I’m delighted that Reidy is returning to the club.
“He had a massive impact in our Championship promotion-winning season, but he also has experience of working and playing in the Premier League and knows what it demands.
“He understands the way we work and the culture we like to live at both the training ground and The City Ground, and I’m really pleased that he is coming back to help us continue to grow that.”
