Matt Barrows, hot off a good interview on KBWF (yes, we are stalking you Barrows), reports on Twitter (@mattbarrows), "The 49ers have agreed to a one-year deal with free agent center Tony Wragge, according to a league source."

Also from Barrows' Twitter:

Wragge's signing obviously prompted by Baas' imminent departure. He's now only player on the roster who's started at center, albeit 2 games.
