It was the same kind of tackle that injured Tony Pollard and Patrick Mahomes. The league is checking it out to see if a rules change is warranted.

The tackle that ended Dallas Cowboys running back Tony Pollard's season is under review and could potentially lead to a rule change.
The NFL's Competition Committee will review the "mechanics of the tackle in Pollard’s case," the Washington Post reported on Saturday. Pollard suffered a broken left fibula and high ankle sprain in Dallas' 19-12 loss against the San Francisco 49ers in the divisional round of the NFL playoffs last week.
With 1:24 left to play in the first half, Cowboys quarterback Dak Prescott threw a checkdown pass to Pollard in the middle of the field. As Pollard tried to escape 49ers defensive back Jimmie Ward, he had his left foot caught underneath Ward's weight as Ward brought him to the turf.
