LITTLE ROCK, Ark. -- Arkansas State Police say they launched an internal investigation tied to the March traffic stop of Michael Dyer, the running back who was dismissed by Arkansas State over the weekend.
The investigation has been completed, but authorities will not release details. They say it is a personnel matter and that the agency can't comment further.
Dyer was released from the team Sunday because of an unspecified violation of team rules. During the March 10 traffic stop, Trooper Royce Denney stopped two vehicles, one of which was driven by Dyer. He was ticketed for going 96 mph in a 70 mph zone.
According to the Jonesboro Sun, Denney discovered marijuana and a firearm in Dyer's vehicle. No charges have been filed against Dyer, who was issued a speeding ticket by Denney.
Dyer is a former Auburn star who was recruited to Arkansas State by new coach Gus Malzahn.
The offensive MVP as a freshman in Auburn's victory over Oregon in the 2011 national championship game, Dyer wasn't eligible to play this season for the Red Wolves after the NCAA denied his request to play immediately.
Dyer transferred to Arkansas State in January after he was suspended indefinitely by Auburn coach Gene Chizik for violating unspecified team rules before the Chick-fil-A Bowl.
He was the first Tigers tailback to rush for more than 1,000 yards in each of his first two seasons, including a 1,093-yard performance as a freshman that broke Bo Jackson's school record of 892 yards set in 1982. Dyer rushed for 1,242 yards and 10 touchdowns last season.
