Alvaro Morata and Cesc Fabregas have been ruled out of Chelsea’s Carabao Cup semi-final second leg at Arsenal.
Morata, who has struggled in front of goal in recent matches, has picked up a back injury.
Danny Drinkwater, Gary Cahill and keeper Thibaut Courtois, who all missed Saturday’s win at Brighton, will be assessed ahead of the game at the Emirates Stadium.
But Andreas Christensen, who went off against Brighton after taking a knock to the head, has been passed fit.
“Morata and Fabregas are out. They are not available for the Arsenal game,” said Blues boss Antonio Conte.
“I have to check a couple of other situations to make the best decision for tomorrow’s game, but for sure Morata and Fabregas are out.
“Morata has a problem in his back and he is injured.”
The tie is finely poised after the recent first leg at Stamford Bridge produced a goalless draw.
The winners will face Manchester City or Bristol City in the final at Wembley.
