Chelsea's interim manager Rafael Benitez has confirmed that both Gary Cahill and Cesar Azpilicueta will be unavailable for selection during tomorrow's FA Cup tie away at Middlesbrough.
Centre-back Cahill is suffering with a virus, while Spanish full-back Azpilicueta has picked up a leg injury.
"Cahill has a virus so he can't play and Azpilicueata has discomfort in his leg so he can't play either," Benitez told reporters.
The winner of the tie will travel to Manchester United in the quarter-finals of the competition on Sunday, March 10.
