Bukayo Saka suffered a major injury scare after being forced off for Arsenal against Crystal Palace.
The England winger was left in real pain before being replaced by Leandro Trossard after 23 minutes.
The 23-year-old was seen sitting on the Selhurst Park turf and clutching the back of his right leg.
And the injury puts Saka in doubt for Arsenal’s clash with Ipswich Town on 27 December, with Brentford next up on New Year’s Day.
The Gunners face Brighton just three days after taking on the Bees, meaning Saka could miss multiple games.
Arsenal look poised to claim all three points without their talisman though, having taken a 3-1 lead in the London derby thanks to a Gabriel Jesus double, his fourth and fifth goals this week after a hat-trick against the Eagles in the Carabao Cup, with Kai Havertz also on the scoresheet.
Saka suffered a similar injury earlier in the season while playing for England in their defeat to Greece in October.
The injury eventually kept him out for over a month, missing nine games in total.
