Raiders' Mack gets 5 sacks, catches his own penalty flag in mid-air

Khalil Mack was a beast on Sunday.

The Raiders linebacker tied a team record by sacking Broncos quarterback Brock Osweiler five times in Oakland's surprising 15-12 win.

Denver's offensive line had no chance at all against Mack as you'll see here.

The second-year pro was even impressive during his down moments. After getting held by a Broncos offensive lineman at one point during the game, Mack managed to catch the penalty flag thrown by the ref.
