Dallas Cowboys star Dak Prescott suffered a partial avulsion of his hamstring tendon based on an initial examination, according to NFL Network's Jane Slater.
Slater reported a recovery "typically" requires more than a four-week recovery, though Prescott is soliciting additional medical opinions. That's why the Cowboys haven't officially placed him on injured reserve just yet.
The veteran quarterback picked up the right hamstring injury in Dallas' Week 9 loss to the Atlanta Falcons. ESPN's Adam Schefter reported that the 31-year-old is "expected to miss several weeks." He reportedly was seeking a second opinion that would help the Cowboys determine whether or not to place him on injured reserve, which would rule him out for a minimum of three games.
