Johnny Manziel‘s NFL career may not be over yet.

At a fantasy football convention in Dallas on Saturday, the former Cleveland Browns quarterback told Jon Machota of the Dallas Morning News that he has had a couple discussions with NFL teams about returning to the league.

“I know the situation that I put myself in,” said Manziel. “I know the year I took off and obviously the mistakes that I made. Right now, I’m hopeful. I’m really hopeful.

“I think that I made some progress in that regard. But we’ll see. Whenever I get a call, I’ll do whatever I can to make the most of it.”

Manziel has not played since 2015, when he made six starts while throwing for 1,500 yards with seven touchdowns and five interceptions. He has reportedly not received interest from a team since being released in March 2016, though he sat down for a “get to know you” breakfast with New Orleans Saints coach Sean Payton in February.

The 24-year-old only got a taste of life in the NFL, being active for just 14 games over two seasons, and is hungry to return to the game.

“I think the thing I realized over the past year and the thing I realized from being away from it is really how much you miss it,” said Manziel. “That’s all I’ve known for so long. It’s what I love to do. It’s hard. It’s hard sitting here going through OTA time and going through summer time and then getting ready to go through fall camp and not being part of it.

“But at the same time, I’m really optimistic and hopeful that I’ll get another chance. That’s really what I’m holding out for every day.”
