WATCH: UMD, Texas exchange 'block sixes'

Pick sixes, kick and punt return touchdowns are always exciting plays in football, but aren't that out of the ordinary. Blocked kicks returns, however, happen few and far between and can change the momentum of a game at a moment's notice. 

Rarely do we see a "block six," but Texas and Maryland were lucky enough to deliver it twice. In the same quarter.

In an already wild opening weekend matchup, Terrapins defensive back Antoine Brooks Jr. returned a Texas blocked field goal 71 yards with 11:43 remaining in the second quarter to extend Maryland's lead to 21-7.

Less than 10 minutes later, Longhorns cornerback Holton Hill, who earlier in the game had a 31-yard pick six to start the scoring, matched Brooks Jr. by returning a 65-yard blocked field goal to end a 27-0 scoring run for Maryland.

Texas' Holton Hill is the first player in the last 10 seasons with a pick-six and a blocked field goal return for a TD in the same game.
