Arsenal boss Mikel Arteta has provided an injury update on David Luiz after the 32-year-old went off just five minutes into the second half against Leicester.
The defender was replaced by Shkodran Mustafi at the Emirates, with the German to later lose his position to allow Jamie Vardy to head home the winner.
Prior to his withdrawal, the Brazilian defender looked assured at the back alongside compatriot Gabriel in a sign that their partnership is getting stronger.
And Arsenal missed his leadership at the back when he went off with a muscle injury, before being spotted with ice strapped around his leg in the stands.
Luiz – who already missed the Premier League opener against Fulham due to injury – is now a doubt to face Manchester United at Old Trafford on Sunday.
When asked about his latest setback in his post-match press conference, Arteta said: “I don’t know.
“We’ve lost a few players in the last week or so.
“David had a muscular problem and he couldn’t carry on.
“We’ll have to assess him in the next 48 hours.”
Luiz will surely play no part in Thursday’s Europa League clash against Dundalk, leading William Saliba to potentially make his debut.
