Former Iowa State starting quarterback Jacob Park requested his release from the school and intends to transfer.
Cyclones coach Matt Campbell indicated the request would be honored.
"We wish Jacob the absolute best, and he's done a lot of great things, but if the situation is that he's looking for a new start, then that's the best situation for him," Campbell said in a statement.
Park told the Des Moines Register on Monday that his suspension for the Oklahoma game in early October was due to a failed drug test for marijuana usage. The school announced at the time that Park took an indefinite leave to "work through some personal health issues."
Park passed for 1,181 yards, nine touchdowns and five interceptions in four September games. He didn't play again the rest of the season and divulged Monday that he never practiced with the squad after the week of the Oklahoma game.
"As far as I'm concerned, I'm no longer on the team," Park said. "I haven't been communicated to by anyone on the team. I haven't talked to Coach Campbell since the second week I was gone. (I'm) just kind of now taking my own steps to make sure my future's OK."
Park passed for 2,972 yards, 21 touchdowns and 10 interceptions in parts of two seasons at Iowa State. He started eight games.
