Arsenal's Premier League title hopes have received a blow following Noni Madueke's half-time substitution against Manchester City on Sunday afternoon.
The Gunners salvaged a point late on against Pep Guardiola's side but were forced into a change at the break, swapping Madueke for Bukayo Saka, who was initially a doubt for the game.
Madueke joined Mikel Arteta's side from London rivals Chelsea during the summer transfer window and has made a positive start to life at the Emirates' Stadium.
Arsenal winger Noni Madueke in major injury scare
While the England international did not get on the scoresheet, his performance for Arsenal in their 3-0 win over Nottingham Forest was especially impressive. Madueke's display whilst on international duty also offered Arsenal fans reason to be encouraged for the season ahead.
However, FourFourTwo understands the attacker could be set for an extended spell on the sidelines after a scan on the player's injury.
It is rumoured Madueke's issue is a knee problem, which could see him miss a number of months.
Madueke's injury is likely to give teenager Max Dowman more of an opportunity during what promises to be his breakout season, although, that is scant consolation for Arteta who will miss his new £50 million signing.
"He had an issue very early in the match and he wasn't well enough to continue,” Arteta said of Madueke's condition after the 1-1 draw with City.
The 23-year-old is valued at €40m by Transfermarkt.
