Melbourne Victory coach Kevin Muscat has key selection concerns ahead of his side's A-League clash with Newcastle, with Ola Toivonen and Elvis Kamsoba in doubt.
Muscat said on Friday that Toivonen has been laid low through illness, while Kamsoba requires scans after reporting knee pain during the club's final training session ahead of Saturday night's GMHBA Stadium encounter.
Victory will already be without defender Georg Niedermeier, who was red-carded in last week's 1-1 draw with Melbourne City, and skipper Carl Valeri, who continues his recovery from a hamstring injury.
Toivonen has been a revelation in his first A-League campaign, the towering Swedish striker scoring 10 goals in 13 appearances.
He was a second-half substitute against City after recovering from a knock at training that sidelined him for three weeks and had an immediate impact as 10-man Victory hung on to claim a point.
"Ola has been ill over the last couple of days, so the doctors will monitor that and make a decision," Muscat said.
"It's just a bit of a stomach illness.
"There is a chance (he could miss) ... it depends how he pulls up."
Kamsoba appears unlikely to feature against the Jets after limping out of Friday's training session at Gosch's Paddock.
"It wasn't a knock, he was on his own and he felt a little bit of pain in his knee," Muscat said.
"He'll be receiving scans and it will be in the hands of the physios."
The match is a pivotal one for both clubs for different reasons.
With seven rounds left in the regular season, third-placed Victory can still reel in Perth Glory at the top of the table, while Newcastle are fighting for a finals berth five points behind sixth-placed Wellington Phoenix.
The Jets will need to break a run of three losses to the Victory, which began with last season's contentious defeat in the grand final.
"The reality is that Newcastle are chasing a finals spot," Muscat said.
"Based on that you would assume they are in a certain mindset.
"But we'll concentrate on ourselves ... all the work this week has been on us and how to perform well.
" ... The grand final) is well and truly gone for me ... it was gone by the first game."
Midfielder James Troisi will make his 100th A-League appearance for Victory.
