Vice-Chair Callum Irving said “We have spoken at length over the past two months and chatted through all options. It’s an absolute testament to Andy of how he has approached these conversations with honesty, integrity and reflection.
“It’s still his desire to focus on playing for the next few seasons and the club are fully behind him in that decision. Andy took on the interim role and not only achieved in terms of playing and results, but also carried himself with great class and led by example across the board.
