Arsenal manager, Mikel Arteta, has confirmed that William Saliba and Gabriel Martinelli will miss their Carabao Cup fourth round game against Brighton.
The two players need further tests to find out the extent of their injuries.
Saliba came off injured during the half-time of Arsenals 1-0 win over Crystal Palace, while Martinelli pulled up in stoppage time of that game and limped down the tunnel.
