Cove Rangers co-manager Graeme Mathieson admits they want to succeed in the play-offs for John Sheran.
The Granite City side face Lowland League champions East Kilbride in the first leg of the pyramid play-off semi-final at K Park on Saturday.
The winner of the tie will take on League Two’s bottom side for a place in next season’s SPFL.
Gaffer Sheran is recovering after suffering a heart attack on Sunday with joint boss Mathieson and first-team coach Roy McBain in charge.
Mathieson says Cove now have added motivation to succeed in the play-offs.
He said: “Obviously we have all had a bit of a shock with the news this week.
“But John is recovering and I don’t think focus on the game will be an issue for the players.
“For me as a person it gives me more motivation to go and do it and get promoted.
“I’m sure the lads in the squad will be exactly the same and it will motivate everyone that bit more to get the result on Saturday.
“I have sat down with the chairman, directors and the rest of the management team and we all feel exactly the same.
“We all got a bit of a shock and we all want to go on and do well for the club.
“But we all want to do well for our manager – he’s a great man and we’d love to win it for him as well.”
Sheran returned for a second spell as Cove manager in May 2014.
Mathieson and McBain worked under previous manager Kevin Tindal and were retained by Sheran.
They have enjoyed a trophy-laden time together, helping Cove to eight honours and Mathieson admits promotion this season would be top everything.
He added: “When Kevin Tindal left, myself and Roy McBain took over and then John came back to the club.
“We met and had a chat and decided it was best for me to stay on at the club for continuity.
“We’ve had a great relationship and a really successful time at the club.
“We’ve won three league titles together as well as cups so we’ve had a very good time together.
“If we could get promotion this season it would be the icing on the cake.”
