However, striker Tommy Conway will not play in the promotion decider after picking up an ankle injury in the second leg of the semi-final against Southampton.
Conway, also 23, left the field at St Mary’s in tears with the injury also ruling him out of selection for Scotland’s World Cup squad.
And Hellberg is disappointed not to be able to call upon a player who has featured in every match since the Swede’s arrival in November.
“Through the season, Tommy has been very, very important,” he said.
“Over the last five or six games, it’s been his best spell in terms of how he has run, how dangerous he has been moving into the box, how good he’s been from the left.
“Of course it’s a big blow not having him in the squad, but he will do everything he can to support us. But that’s football, injuries can happen and other people have to step forward.”
