Arsenal midfielder Declan Rice was injured during their 2-2 draw with Tottenham Hotspur on Sunday.
The England midfielder was taken off during the break and Jorginho came on in his place.
Rice emerged with a bandage on his left calf as he made his way onto the bench in the second half.
After the game, manager Mikel Arteta revealed Rice was suffering from discomfort.
"He had some discomfort in his back and was telling us during the first half he was uncomfortable," Arteta told reporters after the match.
When further pressed if Rice was out for short or medium term, he said:
"Hopefully not [out for long]. We have to assess him. It's strange when a player like him asks to come off because he's uncomfortable. Hopefully not, but let's see."
