Sonny Bradley conceded he was going to receive a one-match ban sooner rather than later.
The central defender misses Saturday’s trip to Torquay after picking up his fifth caution of the campaign against Wycombe.
Despite the match being abandoned at half-time for a waterlogged pitch, the Football Association have confirmed the booking still stands.
It means Bradley has been cautioned in five of his 16 Blues matches since arriving from Hull as a free agent during the summer.
Come January, the minimum number of cards to warrant a ban moves from five to 10.
But the 22-year-old believes he was never going to get that far to take advantage of that.
He said: ‘The card system goes up in January and I would have been very lucky to get up to there without getting a one-match ban!
‘I have played every game so far this season, so that’s 16 matches and five yellow cards.
‘It’s not perfect discipline but a suspension was always going to happen.
‘In every team you get bans, I haven’t gone out and looked for a straight red.
‘It’s just been unfortunate silly tackles in games.
‘I have a one-match suspension now and hopefully I can get straight back into the squad after Torquay.
‘We have a decent squad so we will see what happens.’
Joe Devera will be in the frame to move across to replace Bradley at Plainmoor.
That will again put the left-back position up for grabs, with four different players having occupied the spot so far this season.
In addition, Shaun Cooper appeared there as a substitute for the injured Marcos Painter in the Johnstone’s Paint Trophy at Oxford.
Others include Dan Butler and the fit-again Danny East.
