Dallas Cowboys linebacker Sean Lee yet to be cleared for return

Dallas Cowboys linebacker Sean Lee has revealed that he will have to undergo more tests on his neck before he is cleared to return to action.

Lee sustained a neck injury during his side's defeat to the Chicago Bears last week and as a result missed their loss to the Green Bay Packers.

"We have to do more tests with the doctors," Lee told ESPN. "Until they clear me I won't be in there. That's the key. Hopefully they'll clear me pretty soon.

"Obviously I'd like to be back as soon as possible, but I don't know exactly when that is because the doctors have to give me a timetable."

The Cowboys are 7-7 in their season and are second in the NFC East, one game behind the Philadelphia Eagles.
