Wenger will recall Wilshere for the second leg of Arsenal's Champions League qualifier but he will seek advice on his involvement for the foreseeable future.
"He was a bit tired [before the Fulham game] but it was more about giving him a rest," explained Wenger to arsenal.com. "He could have played but it made sense to give him a breather because we're playing every three days at the moment. He is not 100 per cent yet, but he is 90 per cent.
"I'm a bit cautious because he's had a few operations. I don't want to make a mistake on the medical front and overuse him because the ankle is the most important part of any football player.
"I take always medical advice. If the ankle is not inflamed, if he has no pain, then we would not rest the player. If they say there is a little inflamed ankle, we would say 'OK, let's not [play him]. I do that with medical advice.
"I would be a bit more cautious with Jack [than with others]. Until we feel he is completely free from any risk, of course."
