Carlisle United's Harrison Neal is facing suspension after picking up his fifth booking of the League Two season.
The battling midfielder was shown the yellow card for a foul in the Blues' victory at Salford City.
It means the 23-year-old is set to be ruled out of next weekend's trip to Bromley.
Neal was cautioned by referee Ross Joyce after bringing down Salford sub Conor McAleny in the 68th minute at the Peninsula Stadium on Saturday.
The booking followed yellow cards in previous League Two games for Neal against Bradford City, Colchester United, Harrogate Town and Cheltenham Town.
A player is suspended for one game if he reaches five bookings before the 20th game of the season in the EFL. The 1-0 win at Salford was Carlisle's 15th league fixture.
Neal will be the second Blues midfielder to be suspended for the trip to Bromley, with Ethan Robson one game into a three match ban following his red card against Wigan Athletic in the FA Cup.
Both players, though, can play in Tuesday's Bristol Street Motors Trophy game at Morecambe, with that competition regarded as stand-alone regarding cards and suspensions.
Saturday's matchwinner Ben Barclay, plus midfielder Josh Vela, are also walking a suspension tightrope with the duo on four bookings in the league.
Jon Mellish and the currently injured Jordan Jones are on three yellow cards.
