Gerard Cavlan could miss Tyrone's Ulster SFC semi-final clash with Donegal on Sunday week after being sent off in a club game tonight.
Cavlan received a straight red card in the second half of Dungannon's SFC tie against Killyclogher.
Three other players were sent off, but Cavlan's was the only straight red.
Any ban exceeding four weeks will rule him out of club and county football.
Tyrone are already awaiting confirmation of the punishment Ryan Mellon will receive, after he received a straight red in a club game last weekend.
Killyclogher won tonight's game by 0-12 to 0-04.
