Nelson, one of the top targets for NFL MVP quarterback Aaron Rodgers, was injured Sunday in a preseason loss at Pittsburgh. The team said Monday only that he suffered a "significant right knee injury" that would cost him the season.
Green Bay coach Mike McCarthy said the team had hoped for good news in a re-evaluation of Nelson's injury. Instead, the Packers will be without a playmaker who set career highs in receptions (98) and yards receiving (1,519) in 2014.
There was some hope leading up to Monday's MRI since Nelson was moving around on the sideline and walked to the locker room under his own power after the injury. The team is still only calling it a significant knee injury, however reports surfacing from Sunday said it was an ACL tear.
