Lions Pro Bowl center Frank Ragnow declared out for Week 4 with pectoral injury

Detroit Lions center Frank Ragnow has been declared out for Monday night's game against the undefeated Seattle Seahawks with a pectoral injury.

Lions coach Dan Campbell made the announcement Thursday, four days before playing the NFC West-leading Seahawks.

Ragnow is a three-time Pro Bowl player who leads one of the best offensive lines in the league.

The Lions will likely move Graham Glasgow from left guard to center, a position he has played in two of his nine seasons.

Michael Niese, Kayode Awosika and Dan Skipper are potential candidates to start at guard on a reshaped line without Ragnow when the Lions (2-1) host the Seahawks (3-0) on Monday night.
