JONESBORO, Ark. (AP) --Arkansas State coach Gus Malzahn announced the decision Saturday, saying: "I am truly disappointed that it didn't work out here at ASU for Mike. I wish Mike nothing but the best in the future."
The offensive MVP as a freshman in Auburn's victory over Oregon in the 2011 national championship game, 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.
Malzahn, who was Dyer's offensive coordinator at Auburn, helped recruit Dyer to the Tigers before being hired by the Red Wolves after last season.
Arkansas State travels to Lincoln on September 15th, to play the Huskers, without Dyer.
