“It’s Only Preseason” - Jaylen Warren Criticizes Steelers’ Standout Rookie RB After Preseason Opener

Pittsburgh, PA – Pittsburgh Steelers’ starting running back Jaylen Warren has spoken out after the team’s 31–25 victory over the Jacksonville Jaguars in their preseason opener.

While Warren praised Trey Sermon for his breakout performance — racking up 63 rushing yards, a touchdown, and several powerful runs — he also issued a warning about keeping a level head.

"Trey played really well tonight. No one can take that away from him. He was strong, fast, and kept our offense moving," Warren said.

But Warren quickly shifted to a cautionary tone:

"This is only preseason 1. In the NFL, it's not just about one good game. You've got to stay humble and focus on the next one. I feel like Trey was riding a little too high after the game. That can kill a career if you don't keep it in check."

According to team insiders, Warren's comments were aimed at reminding the rookie that the NFL's grind is unforgiving — and that overconfidence can be dangerous.
