Newcastle Jets striker Francis Jeffers has succumbed to an ankle injury and will miss Wednesday's A-League home clash with Gold Coast.
Jeffers was to undergo scans but the injury was only thought to be minor and it's hoped he'll be fit for the Jets' trip to Melbourne Victory on Saturday.
The former English international rolled his ankle after scoring in the 1-1 draw at home with Perth on New Year's Eve.
The 30-year-old had an action-packed cameo, going on in the 56th minute, scoring six minutes later and hobbling off four minutes after the goal due to a collision with goalkeeper Danny Vukovic.
Midfielder Kasey Wehrman, who delivered the pass for Jeffers to head home against the Glory, said it's a shame to lose the marksman.
"Missing him is a big blow ... I thought if he stayed on the pitch the other night for the last 20 minutes, we probably would have won the game," he said.
"I think he's just a bit bruised and battered and we're hopeful he's only out for a week."
Wehrman said confidence was high at Newcastle despite the disappointing result against Perth, who were controversially reduced to 10-men with the dismissal of Billy Mehmet, sent off on 33 minutes.
The Jets went into the Perth game off a 5-2 hiding against Wellington and haven't won since beating the Victory 3-1 at home in round nine in early December.
"We've played enough good home games to go into this match believing we can win but at the moment we are in a bit of a patch where we're not playing as well," Wehrman said.
"We're trying everything we can but sometimes in football it just doesn't happen for you. We need to keep battling through and stick to the game plan and hopefully we'll come out the other side."
Bottom-placed Gold Coast, who are one point from Newcastle, are coming off four consecutive clean-sheets and two wins from their past four games.
Miron Bleiberg's men drew 0-0 with competition leaders Central Coast on New Year's Eve after beating champions Brisbane 1-0.
"They've certainly got some resilience behind them at the moment ... getting a draw against a tough team will see them coming here with their tails up," he said.
Gold Coast scored a 3-1 win at home over Newcastle in round four.
