Arsenal could be without Alexandre Lacazette for the next six weeks following knee surgery.
The Frenchman underwent the operation on Tuesday, which according to the club was ‘a success’.
“He will now undergo a period of rehabilitation,” Arsenal added in a statement (via BBC Sport). “It is envisaged he will return within four to six weeks.”
The 26 year-old who arrived for a club-record fee last summer has enjoyed a steady start to his career in North London. He has nine Premier League goals to his name, but has recently struggled in front of goal.
Lacazette’s goal drought prompted Arsene Wenger to sign Pierre-Emerick Aubameyang in January. Neither striker was able to prevent the Gunners losing their eighth game of the season in the North London Derby on Saturday.
Arsenal are now targeting at the Europa League as the primary route to a return to Champions League football.
Aubameyang is ineligible for their Round of 32 meeting with Ostersunds, which leaves Danny Welbeck as the only recognised striker.
