Arsenal midfielder Jorginho has been ruled out of their Champions League quarter-final second-leg match with Real Madrid on Wednesday with an injury.
The Italy midfielder, 33, was withdrawn in the final few minutes of Saturday's 1-1 Premier League draw with Brentford with a suspected rib injury, meaning the Gunners finished the game with 10 men.
Arsenal are also assessing a knock picked up by Ghana midfielder Thomas Partey.
Arsenal are 3-0 up against European Champions Real as they head to the Bernabeu for the second leg (kick-off 20:00 BST).
Partey, 31, started the Brentford game at right-back but was taken off in the second half after he "felt something", according to manager Mike Arteta.
