Greg Halford is walking a disciplinary tightrope as Pompey head into a crucial period.
Michael Appleton’s side face a gruelling schedule of six matches in 22 days.
Should Halford receive a booking in that time he will be hit with an automatic two-match ban.
The versatile player has had nine bookings so far this season.
He has already served a one-match ban after picking up five yellow cards, ruling him out of the January 2 home match with Watford.
Football Association legislation states should he receive 10 before Sunday, April 8, he will be given a two-game ban.
With three bookings in his last five appearances, he is rapidly heading towards that figure.
Crucially, it would rob Appleton of one of his most consistent performers.
And with the smallest squad in the Football League, he can ill-afford such an absence.
Elsewhere, Tal Ben Haim, left, has racked up eight bookings.
This includes four yellow cards in his last five appearances.
However, he will not face a ban should he receive 10.
Instead the Israeli will be warned over his future conduct.
Ben Haim’s first five bookings were outside the suspension window.
