Chelsea duo Gary Cahill and Diego Costa may miss Sunday's Community Shield clash with Arsenal after suffering injuries in their side's 4-2 penalty shoot-out victory over Barcelona.
England defender Cahill suffered a suspected broken nose after scoring Chelsea's equaliser in the 2-2 draw, whilst Spain striker Costa was replaced by Loic Remy after an hour due to worries over his hamstring which plagued the front man last season.
Boss Jose Mourinho, though, is refusing to rule out the pair until he has a full diagnosis.

Speaking on the injuries, Mourinho was quoted by Sky Sports as saying: "Cahill has a chance of a broken nose, maybe yes, maybe no. If no, perfect. If yes, he will get a mask tomorrow to be ready for Sunday.
"Diego felt a little thing in his hamstring. We believe it is just a feeling, no more than that, but we have to wait."
Chelsea seal morale-boosting victory
Mourinho, however, was full of praise for his side following their performance against the European champions. Eden Hazard opened the scoring with a wonderful solo effort, evading four challenges before slotting the ball past Marc-Andre ter Stergen.
Barcelona hit back with strikes from Luis Suarez and Sandro before Cahill's 85th minute equaliser took the game to penalties.
Alen Hailovic and Gerard Pique were the unfortunate players from the spot for Barcelona, allowing Loic Remy to convert and hand Chelsea victory.
