The Dallas Independent School District has re-opened an investigation into an alleged grade changing scandal involving Grizzlies' rookie Darrell Arthur when he was at South Oak Cliff High School.

"There are too many questions at this time for us to just leave it alone," Superintendent Michael Hinojosa said.

Arthur did not comment on the situation.

If the district finds Arthur did not have sufficient credits in high school, Kansas could have to forfeit any or all games involving him.
