Mark Rypien's wife was on the ground gasping for air and choking after the former Super Bowl MVP struck her ... and it's all on new police video obtained by TMZ Sports.
Rypien and his wife got into an argument in their car on a busy street in Spokane, Washington on June 30 when Rypien says things got physical.
The 56-year-old -- who won two championships with the Redskins in the late '80s and early '90s -- claims his wife, Danielle Rypien, struck him in the head with a cell phone and poured water on him while he was driving.
