Ryan Taylor insists he is ready to grasp his chance if he earns a recall tomorrow.
The Blues striker has been left out of the starting line-up for the past two fixtures, missing the win over Stevenage and the defeat at Shrewsbury last weekend.
The former Bristol City man has been an automatic pick for much of Andy Awford’s reign but accepts he faces a battle to regain his place in the side.
And it remains to be seen whether Awford will keep the faith with the strike partnership of Craig Westcarr and Miles Storey, which he has used in the past two games.
Taylor said: ‘I’m fit and ready to go if I’m selected.
‘Since I came back from injury, my groin has been fine so now it’s down to me to get myself back in the team.
‘It’s tough when you get left out but I have the attitude where I train even harder.
‘There is more competition for places this season and we all know if you aren’t doing the business, you will get left out.
‘I’ve been left out for the past two games so we’ll see what happens against Carlisle.
‘But as soon as I get my next chance – whenever that comes – it’s up to me to take it.’
The 26-year-old has just two goals to his name so far this term and only one in League Two after an injury-hit campaign.
His solitary league strike came against Cambridge back in August, although he recently scored his second of the season in the Johnstone’s Paint Trophy loss to Northampton.
But Taylor maintains his confidence has not been affected.
He said: ‘Every player needs confidence but I don’t feel mine is low at the moment.
‘Different players deal with it differently and some can’t do anything about it.
‘Some are more affected than others.
‘If you are a confidence player, when things aren’t going quite right you are going to struggle.
‘I just try to keep things on a constant level.
‘I try not to get too high when things are going well or too low when things aren’t going quite so well.
‘In football, you can go through a few highs and lows and you don’t want to be too up and down. I try to stay pretty level-headed.
‘When things are going brilliantly, you know there is usually a downer waiting for you around the corner and vice versa.’
