The referee was caught up in a race row in October following the fiery encounter between the Blues and Manchester United at Stamford Bridge, where he will return on Sunday.
The FA ruled that the 38-year-old had no case to answer after Ramires accused the official of insulting the Nigerian during the Blues' 3-2 home defeat to Manchester United on Oct. 28.
Mikel was subsequently fined 60,000 pounds and banned for three matches after threatening Clattenburg in the officials' changing room following the ill-tempered clash, in which Fernando Torres and Branislav Ivanovic were shown red cards and Chicharito scored the winner from an apparent offside position.
Clattenburg returned to action days after being cleared by the FA but has not officiated a Chelsea match since. He will finally return to Stamford Bridge on Sunday as the top-four-chasing Blues host Swansea City.
