A dodgy piece of ham has put Adelaide forward Josh Jenkins in doubt for Friday night's top of the table clash with Geelong at Adelaide Oval.
Jenkins has been under the weather for the past two days after a bout of food poisoning.
He is prepared to do some extra running on Friday morning before giving himself the all clear to face the Cats.
"I'm certainly in some doubt, I haven't done anything yet … but I've certainly improved in the past 24 hours," Jenkins told Adelaide radio station FIVEaa on Wednesday afternoon.
"Yesterday was certainly an ordinary day, but I've turned the corner, hopefully.
"I'm open to even, whether I've got to run around Friday morning as well to know I'm going to be able to give my best because I don't want to be out there if I'm not able to play my part."
Jenkins travelled to Melbourne on Monday afternoon with Crows teammates and officials to attend the funeral of the wife of recruiting manager Hamish Ogilvie.
"We've identified I had the roast ham, which no one else had on the night, so that was the culprit," Jenkins said.
"I felt crook as of Monday night and all of yesterday.
"I was a little bit shocked when I jumped on the scales this morning, I'd lost a fair bit more weight than I expected."
Jenkins said he spent around 17 hours in bed after arriving back in Adelaide at 7pm on Tuesday night.
"Then I would've thought I was a long shot to play, but when I got up, I went for a walk down the beach a few hours ago and I feel a lot better," he said.
"It's not so much getting out there and running around, it's how you pull up after.
"I'm certainly tracking in the right direction."
After a slow start to the season, Jenkins has played a key role for the Crows in the past month.
He's booted 14 goals in his past five games and is also taking plenty of contested marks.
Defender Jake Lever (hamstring) and winger Wayne Milera Junior (calf) also didn't take part in Wednesday's main session.
Lever and Milera trained away from the main group.
Star midfielder and vice-captain Rory Sloane completed the session, but still has to pass concussion protocols before he is cleared to play.
