The Uruguay forward was able to train with Barca on Friday morning after the Court of Arbitration for Sport relaxed the "excessive" elements of the four-month ban incurred for biting Italy defender Giorgio Chiellini during the World Cup.
"I'm very happy to feel like a footballer again and to be with my team-mates," Suarez told the club's official website.
"I was really looking forward to starting. The situation made me feel very uncomfortable. I'm paying for an error I committed and have apologised for, but it needs to be forgotten about. Now I have to think about the future, which is Barcelona, the club I dreamed about playing for."
