The team did not specify Nelson's injury, although many are speculating that it is a torn ACL. An MRI on Nelson's knee reportedly revealed the torn ACL, but everything else in his knee is intact.
Nelson underwent additional tests on Monday, as the team was hoping to receive positive news on their star receiver. The Packers released a statement revealing the bad news regarding their receiver on Monday.
Nelson will need reconstructive surgery and is expected to be ready for the beginning of the 2016 season. The injury was a noncontact injury in Sunday's loss to the Pittsburgh Steelers, in which it appeared Nelson landed awkwardly on his left leg. The injury somehow occurred in his right leg.
Rodgers expressed his displeasure after the game saying "It's difficult losing a guy like that in a meaningless game."
Nelson led Green Bay last season with 98 catches for 1,519 yards and 13 touchdown receptions. After undergoing hip surgery in the offseason, he was cleared to participate at the start of training camp. The 31-year-old is under contract through the 2018 season.
With the number one target down, the Packers will have to turn to Randall Cobb and Davante Adams to carry the load. Cobb had 91 receptions for 1,287 yards and 12 touchdowns in 2014. While Adams caught 38 passes for 446 yards and three touchdowns in his rookie season.
Those two are expected to be the team's starting receivers, as the Packers look to find a way to contend in the NFC.
