Fumbles LostLST

LST stands for fumbles lost in football. Fumbles recovered by the other team — the ones that became turnovers. Other sites write it FL.

How LST is calculated

Counted. Lower is better. LST ≤ FUM.

A fumble out of bounds stays with the offense, and one recovered by a team-mate counts as FUM but not LST.
