Port Adelaide star Robbie Gray is in doubt for his side's top of the table clash with rivals, Adelaide on Saturday night.

Gray, who collected 30 disposals and bagged six goals in Sunday's 89-point win over Fremantle on Sunday, is battling groin soreness.

He managed just one half of football during the pre-season due to the injury, however, the 29-year-old told The Advertiser he is learning to manage the injury and is hopeful he can line-up against the Crows in the Showdown this weekend.

“I’ve had a bit of groin soreness through most of the pre-season,’’ he said.

“I noticed it after a couple of weeks of training when we returned from our Christmas break and it meant I had to back off my training a bit, monitor my loads and unfortunately I obviously wasn’t able to get as much (pre-season) game time under my belt as I would have liked.

“But I think I’ve got on top of things now, I'm doing a lot more strength work and that type of thing and it feels pretty good at the moment, which is good.’’

Gray managed just eight disposals in round one against Sydney and spent limited time in the midfield, but bounced back to be best afield in the side's thumping win over the bottom placed Dockers.

His brilliant game on Sunday was just the sixth time a player has finished with at least 30 disposals and six goals in a match since Champion Data began recording statistics in 1999.
