France defender Saliba was forced off at half-time due to an unspecified injury in the Premier League leaders’ win over Crystal Palace on Sunday.

Brazil forward Martinelli limped down the tunnel with a knock after coming on as a second-half substitute against Palace.

Arsenal boss Mikel Arteta, who revealed Declan Rice will be available to face Brighton after he was also injured against Palace, is unsure how long Saliba and Martinelli will be on the sidelines.
