On the first day of organized team activities, Dallas Cowboys linebacker Sean Lee was helped off the practice field by trainers after suffering an apparent injury.
The extent of the injury was unknown, but video showed Lee expressing his frustration with what could be another setback. He apparently hurt his left knee while being blocked to the ground by rookie guard Zach Martin.
Last year, Lee sat out the final three games with a sprained ligament in his neck and missed all but six games of the 2012 season with a toe injury. Since he signed as the team’s second-round draft pick in 2010, Lee has yet to play a full season.
However, Lee has shown enough ability on the field that he received a seven-year, $42.6 million contract before last season.
While Lee left Tuesday’s practice, quarterback Tony Romo was back on the field throwing passes and working on handoffs just six months after undergoing back surgery.
The 34-year-old Romo, who missed the final game of the 2013 season after the surgical repair of a herniated disk, did not participate in team drills later in the session. Backup and Cowboys newcomer Brandon Weeden worked with the first team, according to reports.
Romo is expected to take about a third of the snaps during the OTAs, ESPN reported.
