Gronkowski has been out of action since undergoing surgery on a torn ACL in his right knee on January 9, and is pleased to be back on the field.
"Definitely a step forward with participating more and more. It's doing well so far, no setbacks or anything. I'm having a blast competing back out there," Gronkowski said, ESPN reports.
The 25-year-old is hopeful of playing in all 16 games this year but he is leaving the decision on whether he will play in a pre-season game to the training staff.
