On Wednesday, he got to tell his side of the story for the first time as part of SEC Media Days. The Heisman Trophy winner said he left camp early because he slept late and missed a meeting.
"It's been a busy summer for me," Manziel said. He also said that he and the coaching staff came to a mutual agreement that he could leave.
"I probably bit off more than I can chew in July, been traveling, been going a lot of places," Manziel said. "I just overslept. I made a mistake and didn't wake up in time when I should have. That's pretty much the end of that."
Rumors flew early on that Manziel stayed out too late the night before and was too hung over to attend the last day of the Thibodaux, La., camp. Camp coordinators said that Manziel was "sick" and unable to come, but Manziel was seen at a bar in College Station, Texas, where his school is located, the day of his return.
Manziel says all of that is just talk, and that he only overslept because he overbooked himself for the summer.
"There's a lot of rumors out there, a lot of talk," Manziel said. "I've been very eager to get a chance to share my side of the story. I missed a meeting. It wasn't anything due to the night prior. It was just simply my phone died, I overslept, I woke up the next morning whenever I did, went and talked to them and it was kind of a mutual decision to get home and get some time to relax."
Broncos quarterback Peyton Manning defended Manziel, saying his own brother Eli had once missed a meeting during passing camp and caught similar flak. Regardless of what happened, Manziel has apologized for the negative attention he brought to the program.
