An injury suffered by Gabriel Martinelli (23) has hit Arsenal while they're down, with the Brazilian joining a long list of first-team players out of action for the Premier League side.
Martinelli broke down during Arsenal's Carabao Cup semi-final second-leg defeat at Newcastle United in midweek.
A hamstring injury will see the Brazil attacker sidelined for over a month, says The Athletic.
The Gunners are already short of numbers in attack with Bukayo Saka and Gabriel Jesus out, with the latter out for the season with an ACL injury.
Compounding the issue was Arsenal's failure to sign a new striker in January, despite an attempt for Aston Villa centre-forward Ollie Watkins in the final days of the market.
