Arsene Wenger has provided a "very positive" update on the fitness of defenders Gabriel Paulista and Per Mertesacker.
Both players were substituted with complaints during Tuesday's 4-0 win over Hull City.
However, Wenger has confirmed that the duo will be available for Sunday afternoon's FA Cup quarter-final against Watford.
"Mertesacker and Gabriel are very positive. There is nothing wrong there, they are both good," he told the club's official website.
However, Wenger added that the extent of midfielder Aaron Ramsey's muscular injury - suffered in the same game - is not yet known.
"There is a small alert, we don't know how bad it is," said the Frenchman.
The Gunners have lifted the FA Cup in each of the last two seasons.
