Tulane safety Devon Walker was taken off the field in an ambulance at H.A. Chapman Stadium in Tulsa, Okla. after having CPR administered to him following an apparent head and/or neck injury in the Green Wave's game against Tulsa on Saturday.

The injury occurred on the final play of the first half, as Walker attempted to make a play on a Tulsa player, but inadvertently collided with his own teammate instead.

Walker stopped breathing at one point after medical personnel removed his helmet and shoulder pads. However, it was confirmed that Walker was breathing and responsive by the time he was loaded into the ambulance.

Walker, a senior from New Orleans, La., was playing in his 31st career game on Saturday. He has accumulated 47 tackles, four pass break-ups, and a forced fumble in three seasons at Tulane.

Below is the hit that injured him.
