Stallworth, suspended indefinitely for killing a pedestrian while driving drunk in Miami, met with Goodell in New York on Wednesday about a possible reinstatement.
In a public statement released Thursday, Stallworth apologized for his actions and vowed to conduct himself.
"I wanted to meet with Commissioner Goodell before making any public comment about the impact of my actions on the National Football League. I want to thank the commissioner for giving me the opportunity to be heard yesterday," Stallworth wrote. "I recognize that there is a difference between the legal standard in my criminal case and the standard to which NFL players are held.
"It is clear that I exercised poor judgment and caused irreparable harm to Mario Reyes, his family, the NFL, its owners, coaches, employees and to my fellow players. Going forward, I am committed to conducting myself in a manner that more accurately reflects who I am and meets the high standard expected of all NFL players. I tried to convey this commitment to Commissioner Goodell yesterday. I respect the Commissioner's authority and I trust his judgment. Whatever he ultimately decides is the appropriate discipline, I will accept knowing that I have profoundly affected the NFL and its relationship with the fans of our game.
"I apologize for my poor judgment. I jeopardized the honor and privilege that I have been given to be an NFL player and to play for our fans. I am truly sorry."
Stallworth was recently released from jail after serving 24 days for a DUI conviction in the death of 59-year-old Mario Reyes.
