Jamie Lyon has two days to prove his fitness with Manly coach Geoff Toovey insisting his co-captain has to get through training if he is to play in Friday night's NRL semi-final against North Queensland.
Toovey said he would not risk going into the sudden-death match without Lyon testing out the calf muscle he strained in Friday night's qualifying final loss to Canterbury.
While the club will wait until midday on Tuesday to decide whether they will contest the high tackle charge that threatens to rub Steve Matai out of the Allianz Stadium clash, Lyon will need to be running by Thursday.
"He wants to play and that's always a good sign," Toovey said.
"We'll have to keep him with some medical staff, but hopefully if possible he'll be training in the next day or two.
