West Bromwich Albion midfielder Paul Scharner has been ruled out of the weekend's match against Arsenal.
The Austrian tore his medial knee ligament during his side's 2-0 loss to Liverpool on Saturday.
"Paul's got a grade one tear to his medial ligament on his left knee," said Baggies assistant manager Michael Appleton.
"It's not a serious one but it is highly unlikely he is going to be fit to play at the weekend."
Scharner joined West Brom in 2010 from Wigan Athletic.
