Chelsea star Hakim Ziyech exited the Uefa Super Cup with a shoulder injury after scoring the opener for the Blues against Villarreal in Belfast.
And Thomas Tuchel has revealed the 28-year-old will be out for two weeks but crucially Ziyech does not require surgery.
Though the Moroccan will miss the Premier League opener against Crystal Palace on Saturday, Tuchel delivered positive news on his diagnosis.
“Hakim will miss the game for sure because of his injury. It will be treated conservatively,” Tuchel said. “The situation is we don’t need surgery, which is very good news for this kind of problem.
“We hope it will continue like this and he will be back on the pitch within the next two weeks. We hope this, we cannot promise, but this is what we hope.”
There was bad news surrounding the condition of N’Golo Kante though, who is now a doubt for the match against the Eagles following a reaction midweek.
“We have some issues with N’Golo Kante,” Tuchel said. “We need to sort it out, it’s from the final.
“Physically it was the worst thing that could happen to us [playing extra-time midweek]. For tomorrow we have to be careful, the decisions have not been made yet who starts, who we push over the line, the recommendations for some is 60-70 minutes.
“Who do we push over this line for another 90 again. The decisions are not made yet, we’ll take our time, we’ll talk to players and the physical department.
“We have one more night to sleep, to eat good, and overcome some difficult moments tomorrow physically.”
Tuchel was happy to welcome Romelu Lukaku though after the Belgian returned to Stamford Bridge in a club-record £97.5m deal.
