The NFLPA believes the Dallas Cowboys were within the non-contact rules for offseason organized team activities when linebacker Sean Lee suffered a possibly season-ending ACL tear last week, according to Ed Werder of ESPN.

Lee injured the knee on a play in which he collided with rookie offensive lineman Zack Martin. The pair fell to the ground, but the Players Association believes that the injury likely occurred immediately before the collision when Lee planted his foot, reports ProFootball Talk's Michael David Smith.

Rules mandate that the practice needed to be non-contact.

The Cowboys' are looking for a linebacker to replace Lee's integral role in their defense, and were reportedly considering Brian Urlacher and Jonathan Vilma to fill the position.
