if by some miracle, bowles does name petty the starter, he probably wouldn't have played more than a series on thursday anyway..Any knee sprain is an actual tear ( to some degree ) of the ligament
So that's the bad news
"So the MC A medial ligament sprain or MCL injury is a tear of the ligament on the inside of the knee, usually a result of twisting or direct impact."
The good news
Most medial ligament injuries do not require surgical treatment.
And again more bad news
A mild MCL injury or grade one sprain should take 3 to 6 weeks to make a full recover.
So I don't know how they let him play thurs
