Neymar has trained with Barcelona two days after hurting his left ankle during a 5-0 rout at Levante in the Spanish league.
Neymar carried out an individual workout on Monday, and was back with his teammates on Tuesday.
The Brazil striker was substituted after scoring during Sunday's match at Levante, after an opponent fell on his leg while they disputed the ball.
Barcelona will seek to maintain its league lead with a fifth win in as many rounds when it visits Malaga on Wednesday.
In July, Neymar broke a vertebra in his back during the World Cup. He recovered in time for the start of the season but then missed the league opener with an ankle sprain.
