Fremantle expect midfield linchpin David Mundy to resume full training within 10 days after injuring an ankle at training earlier this week.
Mundy missed the Dockers' first Patersons Stadium session of the year yesterday morning, but officials are hopeful he will train next week and be back close to full training by Monday week.
Defender Paul Duffield said the club was confident the ankle injury would not disrupt Mundy's NAB Cup campaign.
"I caught up with him the other day and he is fine," Duffield said.
"He is in really good spirits and looking forward to getting back on the track really soon.
"He has worked fantastically hard, he is in great shape and he is a super important player. He will be fine."
Mundy sent a scare through the Fremantle camp on Wednesday when he pulled up short during a stoppage drill and walked from the field, favouring the right ankle he injured in 2011.
He was sent for scans later in the day, but was cleared of major damage.
The 2011 injury, which he hurt again trying to make a return to the team late in the season, disrupted his preparation for the 2012 season.
However, Fremantle are confident his big training workload leading up to Wednesday's injury will hold him in good stead in early-season games.
Duffield said Fremantle players were looking forward to getting match practice in the NAB Cup in the coming weeks, but still had a strong focus on being ready for round one.
"It is more just about getting the players fit and available, everyone ready to go," he said.
"The NAB Cup provides us with a great opportunity to play games against the rest of the competition, but also to completely prime us for round one. I guess as a player you are just looking forward to playing footy again."Duffield trained away from the main group yesterday but is on track to be ready for the start of the NAB Cup after off-season surgery.
