INDIANAPOLIS -- Indianapolis Colts defensive lineman David Parry ended his second NFL season having started all 32 games in his career.

But things have changed for Parry in the six-plus months since.

Parry was arrested and charged with public intoxication and used expletives and derogatory words toward police in Scottsdale, Arizona. He watched as general manager Chris Ballard added players at his position during the offseason, and now there’s no guarantee that Parry will make the 53-man roster.

“Back in February, I made several mistakes. Mistakes I’m not proud of; mistakes I regret, but mistakes that aren’t truly representative of who I truly am,” Parry said Saturday. “I would like to apologize to anyone who I hurt, offended or let down by my words and actions that night. I’d like to thank Mr. [Jim] Irsay, Mr. [Chris] Ballard and Coach [Chuck] Pagano for giving me a second chance, but now it’s on me to earn the trust back of my teammates, the community and the organization and prove that I can be a good representative of the [Colts] both on and off the field.”

Parry agreed to a plea deal with prosecutors in April and accepted two years of probation to avoid jail time for his February arrest. Parry still can’t go into details about the incident because a misdemeanor drunk-driving charge is still pending.

“It was a pretty terrible experience,” Parry said. “I’m more low-key, so people don’t necessarily know the true person that I am unless they get to know me, and that’s tough for everybody to get to do. It was good to come out here and kind of speak on it myself.”

The Colts are giving another a chance, a chance Parry can’t squander on or off the field. Ballard added to the competition level on the defensive line, when the team signed veterans Johnathan Hankins and Al Woods and selected Grover Stewart in the fourth round of the draft. So a roster spot is far from guaranteed for Parry.

“I’m excited to compete,” Parry said. “They brought in some good players, and that’s good for the team. It’s going to be good for me as well. I’m going to have to elevate my play.”
