The Dallas Cowboys could once again be without middle linebacker Sean Lee for some stretch of time. The Cowboys captain suffered a hamstring injury which is expected to keep him out for a couple of weeks, Ian Rapoport of NFL Network reports.

Lee suffered this most recent injury early in the second half trying to rush the quarterback and didn’t return. After the game, he didn’t seem particularly optimistic that this injury will heal too quickly.

“Felt something, some tightness,” Lee said, via Brandon George of The Dallas Morning News. “Hopefully it will be a quick turnaround. Same deal, but you never know. We’ll see. It’s one of those deals.”

Lee is set to have an MRI on Monday to confirm just how serious it is, but given his injury history, there’s a good chance it won’t be too good.

Lee had also tweaked his hamstring the previous week against the New York Giants, which saw him limited in practice and listed as questionable ahead of the Seahawks game. While he started out strongly, his body once again couldn’t quite hold up.

If Lee does miss time, rookie linebacker Leighton Vander Esch is likely to step in and get more playing time on the Cowboys defense. The first-round pick had an impressive showing against Seattle. He tied Lee with 11 total tackles, which included a team-high nine solo tackles.
