Thomas Tuchel has confirmed that Christian Pulisic suffered another hamstring injury in Chelsea's 5-2 home defeat to West Brom on Saturday.
The 22-year-old felt pain in his hamstring at half-time but had hoped to continue for the rest of the match. However, Pulisic pulled up after a brief warm-up ahead of the second half, leading to his substitution for Mason Mount at the halfway point after the the U.S. national team star opened the scoring in the first half.
The latest setback represents his fourth muscle injury this season and eighth overall since joining Chelsea in 2019.
