Conte told the press on Tuesday that, "Morata is out because he's a bit exhausted and there is a problem in his back".
The Brazilian - who has been on the substitutes' bench for his side's last two Premier League games - scored one and made two others as Antonio Conte's men bounced back in style from their surprise weekend defeat to West Ham.
After the loss to West Ham, Conte conceded Chelsea's hopes of retaining their title were now over, yet he is nevertheless backing his players to respond positively at Huddersfield.

"It was a bit frustrating with their time wasting, which was clever on their part, but we were just not at the races". It's disappointing to come off and feel like that. We have to be honest with ourselves.
"We have to sit back and wait for the results tomorrow".
"It's good to always keep the chance for every player to show that he deserves to play. Bakayoko satisfied me with his performance".
All three posed problems early on, but although Pedro did put the ball in the back of the net from an offside position after a Willian pass, they were kept at arm's length by a packed rearguard.

A long-range effort by Mathias Zanka on 63 minutes was the closet in the game the home side had to an effort on the Chelsea goal, but the stinger sailed helplessly over Thibaut Courtois's crossbar.
"I'm happy to play with these players".
"Chelsea have got talent in abundance. At the end we lost the game". "Now we have 11 points less than Manchester City, and they have to play tomorrow".
