Boss Richie Barker says his Crawley side are determined not to let their season "fizzle out" after a 1-1 home draw against Stevenage put a dent in their play-off bid.
The Red Devils sit nine points off a play-off place after drawing for the fifth time in six games and Barker admitted they were not at their best due to poor decision making.
Stevenage, who had defender Miguel Comminges sent off for a second bookable offence, battled for 63 minutes with 10 men to earn a point at the Broadfield Stadium.
Caretaker player-manager Mark Roberts headed the visitors in front five minutes before the break but midfielder Matt Sparrow levelled 10 minutes after the interval with a low finish following a pass from Paul Hayes.
Barker said: "We've only lost once in our last 10 games and it's been a fantastic run but it's small margins. In all five games we have drawn we should have taken more than a point, and that's been the frustrating thing.
"We're nine points adrift and hope to win at Shrewsbury on Monday. We're not throwing in the towel and will fight on while we have a mathematical chance.
"The players are still very upbeat, there's good togetherness and we have the right attitude. We'll go for the freshest team on Monday and we'll make sure our season doesn't fizzle out."
Roberts played down speculation linking a return of former boss Graham Westley to the club, and he said: "That's all speculation. I've no idea who's coming in. The chairman has a shortlist which he's shown us but I'm none the wiser as to who it's going to be.
"The players need guidance and are looking forward to working with whoever comes in. I'm not ready to take the job on.
"I've still got big ambitions as a player that I want to fulfil, despite the fact I've enjoyed the caretaker role."
