Things were looking dire for Baltimore in Monday night's game in Arizona until a special teams breakthrough gave the Ravens new life.

Asa Jackson, signed from the practice squad two weeks ago, sprinted through the middle of the Cardinals' punt team to block Drew Butler's punt with 4:40 left in the fourth quarter. Raheem Mostert scooped it up at the Arizona 5-yard line and was brought down just shy of the goal line. The Ravens scored on the very next play and made a two-point conversion to close within 26-18.

The big play gave the Ravens a shot to tie the game on their final drive, but Joe Flacco's interception in the end zone in the waning seconds sealed their fate and their sixth loss of the season.
