Fogarty was able to finish his side's Round 2 bout with Richmond despite a knee complaint from a nasty fall in the third quarter, with the Crows spearhead receiving treatment on the Adelaide Oval sidelines before returning to the field.
The 23-year-old ended the evening with three goals from his 12 possessions in the 32-point loss, with scans after the match spelling some concern for the Portland product.
A medial sprain was diagnosed on Monday, however further scans on Tuesday have left the Adelaide key forward racing the clock to face Port Adelaide this weekend.
Speaking to 9 News Adelaide, Fogarty was optimistic of his chances, but admitted there's some way to go before being cleared to play.
"The (scan) results will get sent and assessed. But it's feeling really good," Fogarty said of his injury.
"Just a little bit of rest at the moment and then play it by ear.
"I'm not sure (if I'll be playing). I definitely want to but there's a few things we have to get through."
Another rough conduct charge from the weekend has impacted Port Adelaide's plans, with defender Ryan Burton to miss his side's next two matches after a dangerous tackle on Collingwood's Jamie Elliott over the weekend.
Showdown 53 will take place at Adelaide Oval at 7:00pm local time, with Port Adelaide entering the encounter with bragging rights, having recorded 27 wins from their 52 clashes with the Crows.
