Chelsea manager, Mauricio Pochettino has given injury updates ahead of their Premier League trip to Luton Town on Saturday.
The Blues are looking to embark on a good run, following their 2-1 win over Crystal Palace in midweek.
But speaking to reporters on Friday, Pochettino revealed that Mykhailo Mudryk and Romeo Lavia are doubts for the game.
He said: “We need to assess Mudryk and Romeo Lavia also. Lavia felt something also and we need to check.
“I’m a little bit worried as I was trying to change the position with Lavia there as he was struggling to run.
“Hopefully it is a not a big issue and he can be with us again. He’s an important player so it will be a shame if we can’t use him in the next games.”
