Arsène Wenger has named a 19-man squad for the Champions League Semi Final second-leg clash with Villarreal on Tuesday - and revealed Sol Campbell will start.
The England international broke his nose during the 1-1 draw at Portsmouth earlier this month, his first start since the beginning of February.
But with Philippe Senderos ruled out with the knee injury he picked up against Tottenham on Saturday, Wenger will draft in Campbell as his replacement.
"Senderos is out, [so] Sol Campbell will play for Senderos," said Wenger.
"He will start the game. It is a little bit of a gamble because he's not had a number of games but is physically alright and he will be OK."
Meanwhile, French defender Gael Clichy, who has been out of action with a foot injury since early November, also returns to the fold.
Here is the squad in full:
Jose Antonio Reyes
Robin van Persie
