Nemanja Matic will return to the Chelsea line-up for Wednesday night's meeting with Paris Saint-Germain.
The Serbian midfielder missed last week's Premier League clash with West Ham United because of an ankle injury he sustained during celebrations of the Capital One Cup triumph on March 1.
But Mastic, who was suspended for the League Cup final win over Tottenham, is primed for action for the Champions League Round of 16 second leg at Stamford Bridge against the French giants says his manager Jose Mourinho.
"We're happy that he's back. He's fit to play," said the Portuguese tactician.
"No problem with his injury, but no football for a couple of weeks and no training too because he was really injured.
"He's ready to play and he's going to play."
