Wade Graham has been knocked out in two of his past three NRL games, but the Cronulla back-rower holds no fears ahead of Friday's preliminary final against North Queensland.
Graham copped his second head knock in the Sharks' qualifying final win over Canberra.
The NSW forward left GIO Stadium in the seventh minute for a head injury assessment and didn't return.
The week off has given him vital time to recover as the Sharks press for a grand final berth against the Cowboys at Allianz Stadium.
"I am fine, I have done all my tests," Graham told AAP.
"I followed the protocol and last Thursday I did my cog test, my computer test.
"I passed that and I could have played but it was good to be able to relax and take a bit of extra time. We didn't have to rush anything."
Graham's return to fitness is a another huge boost for the Sharks who will also have captain Paul Gallen returning from a back injury.
Prop Sam Tagataese is also set to make his return from a shoulder injury that has sidelined him for five weeks.
As the Sharks chase their maiden title, Graham urged his teammates to embrace the pressure and expectation.
"You have to embrace it," he said.
"At the end of the day, there are four teams left from a 16-team competition
"We have done a great job so far to get where we are and we have an opportunity to keep that going.
"The Cronulla community is really happy and really excited. It is the first (preliminary final) since 2008, so it has been a while between big games like this.
"And these are the games you want to play in."
