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 that he will end his brilliant NFL career after the Ravens complete their playoff run.

He 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 almost certainly will be his final home game.

"Everything that starts has an end," Lewis, 37, 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 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."

Coach searches: Oregon coach Chip Kelly appears to be near the top of Cleveland's list of candidates to replace Pat Shurmur.

According to several reports, Browns CEO Joe Banner is already in Arizona and intends to interview Kelly, who is preparing the fifth-ranked Ducks for Thursday night's Fiesta Bowl against Kansas State. An interview could take place as early as Friday.

Kelly has been deflecting questions about his future all week. "I do not know what the future holds," he said Wednesday. "I do know we have a football game tomorrow night, and I'm going to be there."

The Akron Beacon Journal reported that the Philadelphia Eagles and Buffalo Bills also plan to interview Kelly for their coaching openings.

Meanwhile, the Arizona Cardinals have completed an interview with defensive coordinator Ray Horton in the search for a replacement for fired coach Ken Whisenhunt. Next up is former Eagles coach Andy Reid.

Horton also has interviewed with Cleveland and Buffalo, which also has interest in Whisenhunt.

The Kansas City Chiefs also are courting Reid.

Falcons: Offensive coordinator Dirk Koetter has signed a contract extension to stay with the team through next season. Koetter's name surfaced this week as a head coaching candidate in Cleveland, Kansas City and Philadelphia.

Rams: Suspended defensive coordinator Gregg Williams won't return next season, sources told ESPN.com. Williams has not been reinstated by the NFL after he was suspended indefinitely for his part in the Saints bounty scandal. The Rams also let go of Williams' son, Blake, who served as linebackers coach this season.
