Timo Werner picked up a knock during Chelsea’s win at Brighton but is expected to be fit for this weekend’s game against Liverpool.
However, Christian Pulisic, who missed Monday’s victory, looks a doubt for the visit of the champions to Stamford Bridge.
Werner, making his debut along with fellow new signing Kai Havertz, took a kick while winning the penalty which led to Chelsea’s first goal in the 3-1 win at the Amex Stadium.
He completed the full 90 minutes, though, and boss Frank Lampard does not believe there is any cause for alarm.
Lampard said: “Timo took a knock when he won the penalty. It’s more of a dead leg, we hope.
“I’d like to think that if it’s a dead leg then we’ve got a bit of time to get him back.
“And obviously he finished the game after having that earlyish knock.”
Werner was lively up front and his performance suggested he will be a major problem for Premier League defences this season.
Pulisic, who sustained hamstring injury during the FA Cup final, had been training with the rest of the squad and was expected to feature on Monday.
But the American has suffered a setback and is being assessed.
Lampard explained: “Christian was training with us last week but he had a little bit of discomfort a couple of days ago where he was trying to train with us and be in contention to play.
“It would have been a big ask and he’s had to take a few steps back.
“We’ll have to see. That’s one that we don’t have big news on at the minute. We’ll see.”
