Arsenal midweek victory in the Champions League which ended 3-0 saw Sanchez and Campbell pick up a knock which might most likely rule them out of Sunday’s clash.
Arsene Wenger has given update on their injury and insisted they will have to undergo a late fitness test to see if they will be available to make the trip to Carrow Road.
When asked if Sanchez is available to face Norwich, the Frenchman said: “I will have to assess that a bit later.
“Spontaneously it might not be the best moment to rest Alexis but I don’t know. He had a little hamstring alarm but we will see how he recovers from that.
Wenger added: “Campbell had a little calf problem so I will assess all that Friday, latest Saturday.”
