Angry Sheffield chief Damien Bates last night called a behind-closed-doors team practice - after seeing the team slip up at home to Scunthorpe last week.
Bates was annoyed with the performance and has backed up comments made by team manager Joe Screen saying it wasn’t good enough.
And there is little doubt Bates and his managerial colleagues are studying the potential permutations for July when new averages come into effect and there may be scope to strengthen the team.
He said: “It wasn’t good enough on Thursday and we have to put it right as soon as possible.
“We got a good win against Glasgow and then to lose at home again is a big blow for us.
“We called the lads together for a private team practice because any issues they have with machinery we want ironed out before we race again on Thursday night.”
Tigers face Edinburgh in their League Cup semi-final at Owlerton on Thursday – and fans attending can also watch England’s vital World Cup game on screens throughout the stadium.
“It’s important to emphasise that the World Cup will be shown on the stadium TV screens so fans can come along and enjoy both the football and the speedway.
“Edinburgh are a fantastic team and we know how tough it will be but we want to see our fans getting right behind us.
“They are the team of the moment in the Premier League and it will be interesting to see how we cope with them on our own track.”
