Cameron Rayner will complete an interrupted but unbroken run to 50 AFL games when he runs out against the Crows at the Gabba on Sunday.

The No.1 pick in the 2017 draft made his debut in the opening game of his first season in the big time and has not missed since.

While temporary Covid 19 postponement of the season forced him to wait a bit longer to reach the milestone, his form ensured he would get there in the quickest possible manner.

Rayner caught the eye of every recruiter in the country during his Under 18s season because of his match wining ability and he has shown at AFL level his ability to sand up in the big moments.

He says the area of development in his game he is most proud is the pressure acts he wants to make his trademark.

His run-down tackle in the final quarter against West Coast at the Gabba on Saturday night was a defining moment of the 30 point win.

“I try to base my game from the start on pressure,’’ he said.

Dayne Zorko has proved his fitness and will return to the side to take on Adelaide at the Gabba on Sunday.

The Lions’ skipper was a late withdrawal due to Achilles soreness from the side that defeated premiership favourites West Coast by 30 points at the Gabba last week.

He trained strongly this week and was declared fit to play.

Thomas Berry, who made his debut in the round two win over Fremantle and held his place for the following week against the Eagles, comes out of the side.

There are no other changes.

Alex Witherden, Connor Ballenden and Mitch Hinge who were named on an extended bench on Thursday night are the emergencies.
