Ahead of tonightâ€™s meeting, the Scot said: "He has left a big hole, not only on the pitch but in the changing room, because he is a fantastic character - you miss people like that, especially in games where you have to dig in.
"I talked to him the other day, and he is looking forward to coming back. We had a little bit of banter comparing changing rooms and training-ground facilities.
"Ours is a bit shabby in comparison, it seems - they have fingerprint entry to their place - but that's what an unlimited budget does for you."
Back in his old surroundings, Sidwell will be made to feel at home.
"He will get a good reception, because everyone saw how he put himself on the line for us last season even when there was talk of him leaving," Murty predicted.
"He never shirked a tackle and he never stinted in his spadework in the trenches for us. He is a top lad, and we wish him all the best - starting after this game."
