Denver Broncos linebacker Von Miller has admitted that he is yet to discover his best form this season.

Miller missed the first six games of the campaign through suspension and he has 14 tackles, two sacks, four tackles for loss, four quarterback hurries and one forced fumble in his appearances so far.

However the the 24-year-old feels that he is not yet hitting the same heights which saw him named as a Pro-Bowler in his first two seasons in the NFL.

He is quoted in the Miami Herald as saying: "I'm a work in progress. I definitely feel like I could be more productive. And that starts at practice.

"I got to have better practices and I think that will carry over into the game. That's the easiest thing to fix is myself. I go out there every day motivated to get better."

Miller was named 2011 Defensive Rookie of the Year in his debut year.
