Chelsea's Cole Palmer injured in warm-up for West Ham match

Cole Palmer was ruled out of Chelsea's Premier League game against West Ham at the London Stadium on Friday after suffering an injury during the warm-up.

The England international was replaced in Chelsea's starting lineup by Brazilian teenager Estêvão. The 18-year-old was making his first start in the Premier League after arriving from Palmeiras in the summer.

After leaving the warm-up early, Palmer took a seat on the Chelsea bench as the game kicked off.

Enzo Maresca's Chelsea are looking to pick up their first win of the season after a goalless draw with Crystal Palace on the Premier League's opening weekend.
