Per Chelsea's official Twitter feed, the Dutchman said the Spain international could be rested against the Canaries or Stoke City on Saturday with PSG looming in the second leg of their UEFA Champions League round-of-16 tie on March 9:
Though the Stoke clash would be the logical choice of the two in which to rest a key player given it allows more recovery time, the Blues may have need of Costa's physical presence when they host the Potters.
Whenever he's rested, in his place could come January signing Alexandre Pato, who is yet to feature for Chelsea since arriving on loan.
Hiddink said the Brazilian could make his debut on Tuesday but admitted the forward is facing competition from youngsters such as Bertrand Traore for a place in the side, per the club's Twitter feed and ESPN FC's Chelsea correspondent Liam Twomey:
With captain John Terry sidelined after suffering a hamstring injury, Branislav Ivanovic has enjoyed a run of games at centre-back alongside Gary Cahill. The 69-year-old praised their partnership and singled out the Serb's aerial prowess in the wake of his late headed winner against Southampton:
Indeed, with his size and strength, Ivanovic is well-suited to playing as a central defender as well as at his usual position of right-back, but with Cahill and Terry also enjoying a fruitful partnership, he's rarely had the opportunity to feature there.
Hiddink also gave the latest on Terry as the stalwart continues his road to recovery:
Pedro isn't set to feature at Carrow Road, either:
The Dutchman reiterated the club are still hoping to improve on their disappointing position of 11th in the Premier League table and praised his players' attitude as they work toward their goal:
While the Blues are still not yet at their best, they've improved markedly under Hiddink's care since he took over in December, and the 2-1 defeat away to PSG in the Champions League is their only loss under him in all competitions in that time.
Against a Norwich side that have lost six of their last seven league games, Chelsea can take another step on the road to recovery with a win on Tuesday.
