Chelsea have been handed a boost after scans revealed Mason Mount's ankle injury is not as bad as first feared.
Mount limped off after 16 minutes of Chelsea's clash with Valencia after being on the receiving end of a heavy tackle from Francis Coquelin.
Chelsea's night got worse as Ross Barkley missed a late penalty and Rodrigo's goal secured all three points for the visitors in their Champions League group game opener.
Mount is an integral performer in Frank Lampard's side and the Athletic claim the 20-year-old has received positive news about his injury.
A scan performed on Mount's ankle on Wednesday morning showed there was no ligament damage sustained.
The Englishman will have another scan later this week once the swelling completely subsides.
Mount is set to miss Chelsea's weekend Premier League clash with league leaders Liverpool, but will only be sidelined for a short period.
After their game against Liverpool on Sunday, Chelsea welcome Grimsby Town to Stamford Bridge in the Carabao Cup.
Chelsea close out September with a league match against Brighton & Hove Albion.
