Arsenal striker Alexandre Lacazette has been ruled out for up to six weeks after having knee surgery on Tuesday.
The 26-year-old came off the bench and missed a couple of chances as the Gunners were beaten 1-0 by Tottenham in Saturday’s north London derby.
Lacazette had the operation on Tuesday, which Arsenal described as “a success”.
“He will now undergo a period of rehabilitation,” Arsenal added in a statement. “It is envisaged he will return within four to six weeks.”
It leaves the Gunners with Danny Welbeck as the only recognised senior striker for Thursday’s Europa League last-32 tie with Ostersunds FK.
New signing Pierre-Emerick Aubameyang is not eligible to play in the competition.
