Queens Park Rangers have confirmed that Charlie Austin and Jamie Mackie have both been sidelined by hamstring injuries.
The attacking duo suffered the complaints during last Friday's 4-0 defeat at the hands of Fulham at Craven Cottage.
A scan has revealed that this season's leading goalscorer Austin sustained an acute muscle problem, which will keep him out of action for around four weeks.
However, Mackie could be absent for up to 12 weeks after an assessment revealed that he tore his right hamstring during the encounter.
Austin has scored seven goals for the R's this term, while Mackie is yet to have found the net.
