Chelsea boss Jose Mourinho says defender Gary Cahill and striker Diego Costa will this week be assessed ahead of Sunday's match against Arsenal.
The two were involved in last night's penalty shoot-out win against Barcelona.
The Blues will now shift their focus to Sunday's FA Community Shield at Wembley, eager to win their first trophy of the new season.
"My first thought when I got on the pitch was the amazing colour of the game," Mourinho told reporters.
"The crowd was beautiful. The blue guys and the Barcelona people were together. There was lots of colour. The screens were amazing.
"Barcelona were not worried about winning or losing. They were training - the same as us. It was not a tactical game. It was two teams looking for the best intensity, the best form.
"For me it was fantastic. I thanked Luis Enrique a lot for what they gave us. It was just what we needed.
"It was 2-2; it could have been 4-4. The penalties mean nothing for us, nothing for Barca but for the people it means a lot. The 70,000 or so people that were here go home happy.
"It was good promotion for soccer in the US and good for the promotion of our clubs.
"[Gary] 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."
