Chelsea are sweating on Thiago Silva's fitness ahead of the Carabao Cup final after the Brazilian defender limped out of Monday night's 3-1 win at Crystal Palace.
The 39-year-old injured his groin sliding in to block a shot by Palace's Jean-Philippe Mateta around the hour mark and could be seen shaking his head when going off.
Chelsea manager Mauricio Pochettino later confirmed Silva felt something in his groin and would be assessed on Tuesday.
Any potential problem would add to a growing injury list for the Blues ahead of their trip to Manchester City in the Premier League on Saturday and the Carabao final with Liverpool at Wembley on February 25.
