The Drive 7 Aspar rider was forced to miss the last race in Italy because of the injury which he has battled throughout the season, but he is hoping he will be able to race in Montmelo this weekend.
Hayden intends to use free practice to assess his wrist and is hoping to line up on race day if team doctors give him the all clear to compete.
Speaking to the official MotoGP website he said: "I am happy to say my hand is feeling better than before surgery and in Mugello, but it's only been a few days since the operation so still a bit too early to say how I will be in Barcelona.
"I think I will try in FP1, see how I feel and discuss it with my team and doctors to know if we can do the race.
"I would hate to miss another race after two non-point scores but also we have to be smart and think long term and make a decision with both our heart and head. So we wait and see, hope for the best.
"This track is fast and challenging with a bit of everything, and a lot of long corners with a lot of lean angle where if we can make the soft tyre last it can help us be more competitive with the extra edge grip."
