Sydney forward Joel Amartey is facing a potential stint on the sidelines after suffering a hamstring injury in Friday's clash with Collingwood.
Amartey came from the field at Adelaide Oval in the second term of the match after stretching for possession on the wing, with the Swans tall receiving treatment on the interchange before eventually making his way down to the rooms.
The Swans soon made the call to sub Amartey out of the match, with young onballer Angus Sheldrick injected into the contest.
Amartey had three disposals and a tackle to his name before hurting his hamstring, with a low-grade strain still likely to rule the 25-year-old out for Round 6 at the very least.
"He'll have scans on his hamstring," coach Dean Cox said of Amartey's injury post-game. "The severity? We need to find out.
"That certainly wasn't ideal. He's been pretty consistent for us. It's very unfortunate for him that he has another soft-tissue (injury).
"We're going to work through and support him."
The setback for Amartey comes after a strong start to the season for the Sydney attacker, who booted four goals in the club's Round 4 win over North Melbourne.
Amartey had booted two goals the week prior and three majors in the Swans' season opener against Hawthorn to lead his side's goalkicking for the year to date.
Amartey's injury comes as fellow tall forward Logan McDonald nears his return to top flight football for the first time since last year's grand final loss.
McDonald has featured for Sydney's reserves in the VFL and is likely to be in the frame for a return next week when the Swans face Port Adelaide, with Amartey likely unavailable due to his injury.
"We had a VFL bye this week, so they'll have a big session back home," Cox said on McDonald's return chances.
"We'll have to discuss that when we get back early in the week, about what it looks like with him ahead of the ball as well."
Hayden Mclean and Peter Ladhams have held forward target roles in the early rounds of the season under Cox while supporting ruckman Brodie Grundy in the middle.
