Ex-Broncos defensive lineman Derek Wolfe hunted a massive mountain lion in Colorado this week ... and at the end of the day, a wild photo shows the Wolfe got the better of the big cat.
The former NFL player detailed his insane journey to nab the mountain lion in Grant on his social media page Thursday ... saying it all started after he got a call on Tuesday that the animal was terrorizing a rural neighborhood in the city.
Wolfe said he was told the mountain lion had killed two of a woman's dogs .
