Are the Dallas Cowboys to blame for Sean Lee's injury?
The star linebacker suffered what's expected to be a season-ending injury during OTAs Tuesday when he slipped while attempting to get past rookie O-lineman Zack Martin.
By rule, OTAs are non-contact practices, and the NFLPA is "monitoring" the situation to see if there was any negligence on the part of the Cowboys' coaching staff.
"The NFLPA, which declined official comment, is monitoring the situation," writes Fox Sports' Mike Garafolo. "Several officials have seen the clip online and have spoken with Cowboys players, but the union has not yet made a formal request for the team's tape of the practice."

Garafolo continues, noting that Dallas is unlikely to draw an investigation from the union.
Whereas the union could charge the team with neglect if there were a clear, objective violation -- e.g. if OTAs ran longer than the allotted 90 minutes or if a team scheduled an excessive number of sessions -- there likely won't be much said about the team's role in Lee's injury.
Several players from other teams who viewed the clip of Lee's injury told FOX Sports it was standard OTA speed and contact. (The players requested anonymity because they didn't want to get involved in another team's business.) Two players, both of whom have suffered non-contact ACL injuries, believe Lee would've torn his ACL even if Martin didn't hit him.
It appears this was nothing more than a freak (and costly) injury, though the NFLPA is understandably doing its due diligence.
