Swansea City midfielder Kemy Agustien looks likely to miss the next six weeks after suffering a hamstring injury at the Emirates on Saturday.
The Dutchman limped off in the second half and as a result, Swans assistant manager Colin Pascoe confirmed that the 25-year-old is now set for a spell on the sidelines.
"It's a blow losing Kemy because he has been a strong player for us," Pascoe told the South Wales Evening Post.
Pascoe, who took charge of Saturday's 1-0 loss to Arsenal because of the death of manager Brendan Rodgers' father, did however say that winger Wayne Routledge is ready for a return to action.
"We didn't want to risk Wayne at Arsenal, but he should be back next Saturday."
Swansea welcome West Brom to the Liberty Stadium on Saturday.
