HOUSTON >> Texas A&M quarterback Johnny Manziel has been suspended for the first half of the Aggies’ season-opener against Rice on Saturday for what the school said was an “inadvertent” violation of NCAA rules by signing autographs.

The school issued a statement Wednesday saying it declared the Heisman Trophy winner ineligible and that the NCAA agreed to reinstate Manziel after he sits out the first half.

“I am proud of the way both Coach Sumlin and Johnny handled this situation, with integrity and honesty,” Texas A&M Chancellor John Sharp said in the statement. “We all take the Aggie Code of Honor very seriously and there is no evidence that either the university or Johnny violated that code.”

Manziel was being investigated by the NCAA for allegedly accepting money for signing autographs for memorabilia brokers, which violates NCAA rules and could have led to a much longer suspension. ESPN first reported the allegations against Manziel earlier this month.

According to the statement, Texas A&M and the NCAA “confirmed there is no evidence Manziel received money in exchange for autographs based on currently available information and statements by Manziel.”

Conditions for reinstatement include Manziel discussing his actions with teammates and A&M revising how it educates student-athletes about signing autographs.

“Student-athletes are often asked for autographs from fans, but unfortunately, some individuals’ sole motivation in seeking an autograph is for resale,” said Kevin Lennon, NCAA vice president of academic and membership affairs. “It is important that schools are cognizant and educate student-athletes about situations in which there is a strong likelihood that the autograph seeker plans to resell the items.”
