Maresca, Chelsea manager, acknowledges setback for Lavia

The midfielder will not be available for today's match against Wolves due to an injury.

Before kickoff, Maresca confirmed:  "Romeo has a small hamstring issue but not a huge concern."

The injury-plagued midfielder started for Chelsea in last week's defeat to Manchester City.

He also came on for the final six minutes against Servette in the Europa Conference League first-leg playoff.
