Premier League leaders Arsenal remain without injured pair Gabriel Jesus and Mohamed Elneny.
This game is also likely to come too soon for Emile Smith Rowe, who is nursing a thigh problem.
Reiss Nelson, who has not played since November because of a hamstring issue, has resumed full training and could feature.
Brentford will monitor injury doubts Pontus Jansson, Shandon Baptiste and Frank Onyeka.
CHRIS SUTTON'S PREDICTION
This is a really interesting game because of Arsenal's last result, their defeat at Everton, and Brentford's form - they are unbeaten for nine games now.
The Gunners are the only team who have beaten the Bees on their own patch this season - a really impressive 3-0 win in September which was the first real statement that Mikel Arteta's side meant business in the title race.
