Chelsea enjoyed a wonderful start to the season under Maresca but have slowed down in recent weeks, winning two of their last eight Premier League games to fall 16 points behind leaders Liverpool.
While he was on a run of eight games without a goal before injury struck, the former Villarreal star has been the focal point of Maresca’s attack, starting every league game bar the trip to Southampton in December.
Chelsea have been dealt a huge injury blow with Nicolas Jackson sidelined with a hamstring injury until April.
He will also miss Premier League matches against Aston Villa, Southampton, Leicester City and Arsenal.
Jackson has scored nine goals this season and laid on five assists – all coming in the Premier League.
