Johnny Manziel admitted that he is not ready to start for the Cleveland Browns in their 2014 season opener against the Pittsburgh Steelers on Sept. 7 at the Heinz Field.

Manziel, the 22nd overall pick in the 2014 NFL Draft, said that he is not prepared to start if the season will start today, saying that he just only played in one preseason game.

"I don't think I'm ready for Pittsburgh right now," Manziel said via ESPN. "I've only played one game."

The rookie quarterback, who completed 7-of-11 passes for 63 yards and had 27 yards rushing in their preseason game against the Detroit Lions, quickly added, though that could change before their season opener against the Steelers.

"It's just right now, second preseason game, I'm not ready to go out and start Week 1 because there's a lot of time left until that point," Manziel said.

Manziel is also adjusting in his life as a professional football player, admitting that he was confused by their training schedule, which was the reason why he was late during a team meeting last week.

"I think we had to come in at 7:30 and it was the only day that we had had to come in at that time throughout camp," Manziel said. "I was on time for what I thought was our normal 8:15 meeting time. It was a misinterpretation, a misreading of the schedule. I sat down with coach [Mike] Pettine and talked to him and we handled it and we've moved on."

Following the incident, Pettine named Brian Hoyer as the starting quarterback in their second preseason game against the Washington Redskins on Monday.

Manziel insisted, though, that being late in the meeting did not affect his coach's decision to name Hoyer as starter, admitting that he still has a lot to learn before getting the starting spot.

"I'm still learning. I'm still growing," Manziel said. "This is my second game. My expectations aren't through the roof. It's go out and compete extremely hard, be a leader for those guys, whatever group I'm with, and we'll see what happens."
