Port Adelaide don’t know if more players will suffer the viral meningitis outbreak at the AFL club.

“It’s sort of a wait and see,” defender Jackson Trengove told reporters on Thursday.

“I don’t think you can really test for it too much. If you feel crook, you feel crook.

“A couple of blokes were sort of questionable and they sent them home to take care of themselves and they pulled up really well.”

Two of Port’s AFL-listed players, John Butcher and Jarrad Redden, were hospitalised and three of the club’s youth academy have since been diagnosed with the illness.

Trengove was with Butcher the night before sickness struck.

“Some blokes, it just hit them,” he said.

“Johnny Butcher, I was with him on Thursday night and he was fine. And on Friday morning, he was in hospital.

“It’s just one of those things that goes whack. But the other blokes who were around him didn’t get crook.”

Coach Ken Hinkley’s clubrooms have had a hospital-strength clean as fifth-placed Port prepare for Saturday night’s crunch home game against second-placed Sydney.

Trengove will make a key comeback, his first match since ankle surgery five weeks ago.

“We love playing against Sydney, they’re one of the best teams in the competition and we respect them so much,” he said.

“They’re the powerhouse at the moment and really playing some good footy.

“They have got that many good forwards it’s not funny.

“We were having a little bit of a joke with Alipate (Carlile) and a couple of the other defenders of which one do you want to take – it’s a bit of put the name in the hat and pick one out.”
