Arsenal will have to wait a little longer to learn the extent of injuries suffered by Bukayo Saka and Willian.
The two picked up knocks and were replaced during the Gunners' 0-0 draw away to Leeds on Sunday evening.
Willian was taken off at half-time, with coach Mikel Arteta revealing it was not a tactical decision.
"He was feeling something muscular and we had to take him off," he said.
Saka, on the other hand, was forced off in the closing stages of the match after a stud appeared to connect with his knee, moments after missing a glorious chance that could have won the Gunners the match.
Arteta gave an update on Saka's injury as well, saying;
"He was in pain," said the manager.
"We're going to have to assess with the medical staff how bad it is, but it looked like a pretty bad challenge and he was in pain so we decided to take him out straight away."
The Gunners were forced to settle for the scoreless draw, failing to score in a third successive match.
