Cougars are one of four teams battling to avoid the final relegation spot.
March said: “We’re still in the mix for relegation, so we’ve got to fight for our lives.
“We can only concentrate on what we’re doing in-house.”
But March, who has no new injury concerns ahead of the match against second-placed Rovers, is demanding a solid start from his team.
He said: “We’ve started slowly for three weeks on the bounce. When you do that against good sides, you’re always chasing the game.
“We can’t start playing when we’re behind, we’ve got to start playing from minute one – and that’s what we got to do this week.”
Hay said: “You can’t go into games thinking you’re going to be able to play and win; you’ve got to put in the hard work and effort.
“You generally get what you deserve.”
