Chelsea will be without Hakim Ziyech and Callum Hudson-Odoi for their last Champions League Group stage clash against Krasnodar on Tuesday night.
Ziyech picked an injury against Leeds United on Saturday night and could be out for a couple of weeks.
Speaking ahead of the match, manager Frank Lampard said the winger will be assessed in the coming days, but they are optimistic it will not keep him out for long.
"He is going for a scan this afternoon, so I will have more information later," said Lampard. "I hope it's a minor injury. Long-term I am not worried about him at all,"
The manager also spoke about Callum Hudson-Odoi, who also picked an injury last timeout.
"Callum Hudson-Odoi is also out with a hamstring problem," he added.
The two shouldn't be a concern though as the rest of the team is largely available.
Chelsea are through to the next round of the Champions League, and that provides Lampard with a chance to rotate his squad.
