If Andy Reid wants another NFL head-coaching job after the Eagles let him go later this month, he'll have no trouble finding one. Wherever he winds up, though, he's going to need a new offensive line coach.

Howard Mudd acknowledged to the Daily News Thursday what most people had already suspected – he's calling it quits after the season.

``I decided quite a while ago,'' the 71-year-old Mudd said. ``I gotta go be a grandpa. That was the plan two years ago and Andy talked me out of it. But this time, it's going to be permanent.

``I told my wife last night, I really like coaching. But it's time.''

Mudd is one of the league's best offensive line coaches. He's been coaching NFL offensive lines for 37 years. Spent 12 years with the Colts before retiring after the '09 season.

Reid coaxed him out retirement last year after making the controversial decision to switch Juan Castillo from offensive line coach to defensive coordinator.

The offensive line was one of the Eagles' biggest concerns at the start of the '11 season. By the end of the year, it was one of their greatest strengths.

Injuries wreaked havoc with Mudd's unit this season. He lost All-Pro left tackle Jason Peters to a ruptured Achilles tendon last spring. Center Jason Kelce tore his ACL in Week 2 and right tackle Todd Herremans suffered a season-ending foot injury in Week 9. Right guard Danny Watkins also was out for more than a month with an ankle injury.

Is he glad he came back?

``Oh yeah,'' Mudd said. ``It's all about the people. The players you coach. The coaches you work with. The owner. But it's time.''
