OWINGS MILLS, Md. (AP) -- Ray Lewis spent 17 seasons instilling fear in his opponents while serving as an inspirational leader for the Baltimore Ravens.
Now he's poised and eager to become a full-time dad.
Lewis announced Wednesday he will end his brilliant NFL career after the Ravens complete their 2013 playoff run.
Lewis has been sidelined since Oct. 14 with a torn right triceps. The 13-time Pro Bowl middle linebacker intends to return Sunday to face the Indianapolis Colts in what will almost certainly be his final home game.
''Everything that starts has an end,'' the 37-year-old Lewis said. ''For me, today, I told my team that this will be my last ride.''
Lewis will walk away from the game because he wants to spend more time with his sons. While working to return from his injury, Lewis watched two of his boys play on the same high school football team in Florida. He intends to see Ray Lewis III perform as a freshman next year for the University of Miami, where the elder Lewis starred before the Ravens selected him in the first round of the 1996 draft.
''God is calling,'' Lewis said. ''My children have made the ultimate sacrifice for their father for 17 years. I don't want to see them do that no more. I've done what I wanted to do in this business, and now it's my turn to give them something back.''
That's why Lewis will pull off his No. 52 uniform for the last time after the Ravens lose or claim their second Super Bowl title.
''It's either (that or) hold onto the game and keep playing and let my kids miss out on times we can be spending together,'' Lewis said. ''Because I always promised my son if he got a full ride on scholarship Daddy is going to be there, I can't miss that.''
Lewis was the AP Defensive Player of the Year in 2000, the same season he was voted Super Bowl MVP following Baltimore's 34-7 rout of the New York Giants. Lewis was also Defensive Player of the Year in 2003, and is the only player in NFL history with at least 40 career sacks and 30 interceptions.
''I never played the game for individual stats,'' Lewis said. ''I only played the game to make my team a better team.''
Lewis has been with the Ravens since they moved from Cleveland. After being drafted 26th overall in Baltimore's first draft, Lewis became a fixture at middle linebacker - and a beloved figure in Baltimore. He remained that way even after his alleged involvement in a double-murder in Atlanta in early 2000.
In June of that year, a judge approved a deal allowing Lewis to avoid murder charges and jail time by pleading guilty to a misdemeanor and testifying against two co-defendants. Within a year, Lewis was in the Super Bowl, leading the Ravens to their only NFL championship.
Hundreds of games later, he's ready to call it a career.
''I'll make this last run with this team, and I'll give them everything I've got,'' he said. ''When it ends, it ends. But I didn't come back for it to end in the first round.''
The news of his decision to retire quickly resounded throughout the NFL.
Colts coach Chuck Pagano, who served as Lewis' defensive coordinator last year, said, ''I thought, shoot, the guy could play forever and would play forever. Great person, great man, great player, just an unbelievable human being - what he's done for that organization, that city and for that matter, so many people. He's obviously a first-ballot Hall of Famer and will be sorely missed.''
Green Bay Packers coach Mike McCarthy said, ''I don't know, at least in my time in the league, if there's been a defensive player that's had as big an impact. ... He's really an incredible example of leader. Talk about somebody opening up his chest and giving it to his football team.''
Lewis was respected by his peers, too, even those who were on the receiving end of his crushing tackles.
''He definitely inspired me,'' Minnesota Vikings running back Adrian Peterson said. ''Just the passion and how he is dedicated to his craft to be the best. You don't see too many guys who play like that. That's definitely what makes him the best linebacker to ever play the game.''
Indianapolis standout linebacker Dwight Freeney said, ''He's meant a lot to the league in general, but defensive guys especially. This is a league where the most focus goes on offense, quarterbacks and running backs, and very few times do you see a defensive guy get highlighted in commercials or whatever. You see Ray on there, so it's kind of like he's one of us. And you feel good when you see him, the things he's done for the game and how he motivates guys.''
Lewis is the key figure in a defense that has long carried a reputation for being fierce, unyielding and downright nasty. He led the Ravens in tackles in 14 of his 17 seasons, the exceptions being those years in which he missed significant time with injuries (2002, 2005, 2012).
Baltimore linebacker Terrell Suggs, who is almost always upbeat, said of the announcement: ''It was sad. It affected me, because for the past 10 years of my career I've been sitting right next to the man and going to war on Sundays. It's going to one hard last ride, and we need to make it one to remember.''
When Lewis tore his triceps against Dallas, it was feared he was done for the season. But he would have none of that.
''From the time I got hurt, everything I've done up to this point has been to get back with my team to make another run at the Lombardi (Trophy),'' he said.
Well, not everything. Lewis spent time watching his boys play football, which caused him to call his rehabilitation ''bittersweet.'' After spending countless hours from Monday through Thursday working to return from the injury, he hopped on a plane toward Florida to be with his boys.
''I got to be there every Friday,'' Lewis said. ''Me being who I am, not having a father myself, that damaged me a lot. I didn't want my kids to relive that.
''One of the hardest things in the world is to walk away from my teammates. But the now I'm going to step into other chapters of my life.
''I knew I couldn't split my time anymore. When God calls, he calls. And he's calling. More importantly, he calls me to be a father. It's OK to be Daddy. Yes, this chapter is closing, but the chapter that's opening is overwhelming. That's what excites me the most.''
Lewis could have made the announcement during the offseason.
''I think my fans, my city, I think they deserved for me to just not walk away,'' he said. ''We all get to enjoy what Sunday will feel like, knowing that this will be the last time 52 plays in a uniform in Ravens stadium.''
