DETROIT -- Four-time Pro-Bowl center Frank Ragnow is coming out of retirement and returning to the Lions.
He has decided to unretire and return to the Lions because he "loves the game," a source told ESPN's Adam Schefter.
Wednesday was the deadline for Ragnow to come out of retirement and be eligible to play this season, sources added to Schefter. If a player is on a club's reserve-retired list, he must be reinstated before that team's Week 13 game. Detroit hosts NFC North division rival Green Bay on Thursday in its annual Thanksgiving Day appearance.
