Cornerback Aaron Berry has a checkered past and is coming off a significant injury, but new Browns coach Mike Pettine hasn’t given up on him yet.

Pettine was instrumental in Berry receiving a chance to redeem himself after a couple of arrests in a short period of time caused the Detroit Lions to cut him two years ago.

“It represented a turning point in my life,” Berry said this past Tuesday after the Browns wrapped up a practice during organized team activities. “I think it would for anybody. Going through that at this stage in your life, especially being in the NFL, you’re not going to get too many chances. They come and they go. What do they say [NFL] stands for, ‘Not For Long?’ ”

Now Pettine is at the heart of Berry’s latest comeback attempt as he tries to rebound from a torn anterior cruciate ligament. Berry signed with the Browns on June 2.

“I think everybody would be worried coming off an ACL, my past and not being able to stay on the field,” Berry said. “Of course, I’d be worried, but you’ve got to believe in God and stay ready and when the opportunity comes take advantage of it.”

The 5-foot-9, 190-pound Berry hasn’t played in the NFL since he appeared in seven games as a backup for the New York Jets in 2012. At the time, Pettine was in his fourth and final season as the Jets’ defensive coordinator, and new Browns defensive coordinator Jim O’Neil was their defensive backs coach.

After Pettine and O’Neil left the Jets to join the Buffalo Bills, Berry suffered a torn ACL last July and missed the entire 2013 season.

“It was tough last year getting hurt the first day of training camp, especially coming in with an opportunity to get a starting job,” Berry said. “[The Jets] had a big [expectation] for me. That’s just another obstacle I had to take in my life. So I’m real pleased with the opportunity I have now, and I feel that I’m healthy and ready to go.”

Berry, who’ll turn 26 on June 25, participated in individual drills upon joining the Browns in OTAs. He has been medically cleared, Pettine said, and will likely take reps in 11-on-11 drills during the team’s three-day mandatory minicamp, which will run Tuesday through Thursday.

“He’s a great competitor,” Pettine said. “That’s one of the reasons he’s here. I was fortunate to be around him in New York, and when he’s healthy, I think he can be a guy that really fits our style of play. He’s very confident. He’ll get in your face, he’ll cover you and he’ll tell you about it.”

Berry had his best season in 2011. He started three of the 11 games in which he appeared with the Lions and had 31 tackles and 11 passes defensed.

He was projected to become a starter for the Lions in 2012, but they released him that summer in the wake of two arrests. One was for allegedly pointing a gun at three people in a parking lot in his hometown of Harrisburg, Pa., and the other for suspicion of DUI and related charges.

“Coming into this league not having too much and then getting some money, I was young [and] I made some mistakes,” said Berry, who signed with the Lions in 2010 as an undrafted free agent from the University of Pittsburgh. “I put it behind me definitely. I’m just ready to move forward with my life. That’s not the type of person I am. If you get to know me, you’ll know that that’s not the type of person I am at all. That’s what I’m going to show everybody in Cleveland.
