Darius Leonard keeps racking up NFL accolades.

The Indianapolis Colts' rookie linebacker added an AFC Defensive Player Of The Month award to his tally Thursday one day after he earned the AFC Defensive Player of the Week nod for his play against the Tennessee Titans. Leonard recorded 49 tackles, three tackles for loss, one sack, a quarterback hit and an interception in five December games.

Leonard, who helped the Colts go 4-1 and make the playoffs in that span, is now the second Colts rookie to win a player of the month award. Running back Edgerrin James won in November 1999. The last defensive player for the Colts to win was Robert Mathis in December 2013.

Whether or not the Colts' young star wins the NFL Defensive Rookie of the Year award has yet to be seen. Leonard is a Pro Bowl alternate.
