Chelsea manager Frank Lampard has revealed that he withdrew Christian Pulisic as a precaution following an injury he picked as he scored their second goal in the 2-0 win over Crystal Palace on Saturday.
The American was the quickest to react to Mitchy Batshuayi's deflected ball off a defender to head in his fifth goal of the Premier League but appeared to have hit the post as he landed.
He was then withdrawn and seemed to be limping, with Callum Hudson-Odoi taking his place going into the last 10 minutes of the match at Stamford Bridge.
Speaking after the match, Lampard praised the former Borussia Dortmund and was optimistic he will recover in time for their next assignment.
"He came off with a bit of an injury. He has had a hip problem," Lampard said, before praising the former Dortmund winger's adaptation to the Premier League.
"Christian came from another league, it is tough. I know he has huge talent and he has shown that,"
Pulisic has put his early-season struggles and troubles behind him to star for the club and has become a key member of the side in the last couple of matches.
At the Bridge on Saturday, Tammy Abraham gave Lampard's boys the lead seven minutes after the re-start, following a sleek move started by Pulisic, before a clever flick by Willian set the England international in a one-on-one situation with the keeper.
The win saw Chelsea temporarily move to second on the log before they were dislodged by a high-flying Leicester that saw off Arsenal 2-0.
