The initial prognosis for Green Bay Packers wide receiver Jordy Nelson's knee injury suffered during preseason action against the Pittsburgh Steelers on Sunday is, apparently, not good. Nelson, per a report from Ian Rapoport of NFL.com, tore his ACL. The team is awaiting the results of an MRI to confirm.

Nelson, 30, went down without being touched after a short reception early against Pittsburgh. He has become the No. 1 receiver for and far and away favorite target of Packers quarterback Aaron Rodgers. Nelson finished last season in Green Bay with 98 receptions for 1,519-yards and 13 touchdowns. While the Packers were able to re-sign utility man Randall Cobb this offseason and last year's draft pick Davante Adams is said to be looking set for playing time, there's no downplaying how devastating the loss of Nelson would be for the Pack.

As is often the case with ACL tears, the play looks fairly inoccuous. Nelson's potential absence however, will be significant for a Packers team that came close to reaching the Super Bowl last year and likely has their sights set on a serious run this season. Cobb, Adams and Ty Montgomery will be asked to shoulder the load if Nelson is indeed done for the year.
