Costa, Hazard injured as Chelsea go out

Costa, Chelsea's goal-scorer, hobbled off shortly before Zlatan Ibrahimovic scored in the 67th minute to give PSG a 2-1 win on the night and complete a 4-2 aggregate victory.

Hazard left the fray late on with a hip injury and was booed by a small number of Chelsea fans as he made his way over to the touchline to be replaced by Oscar.

"We'll see if there is big damage tomorrow (Thursday)," said Hiddink of Costa, who missed Saturday's 1-1 draw with Stoke City due to a minor tendon problem.

"Diego was desperate to play today, although he's not 100 percent fit. I don't know if it became worse.

"I don't hope (think) that it's worse than it was before the Stoke game. Because in two days we have to play another game (against Everton in the FA Cup)."

On the fans' booing of Hazard, Hiddink said: "Yes, they had the right to do what they think. You can express always your feelings. He was also having a little bit of a problem with a late injury on the hip."
