The Saints have signed fullback Zak Keasey to a one-year contract. Keasey, 6 foot, 237 pounds, didn’t play in 2009, but was with the 49’s from 2006-2008 and the Redskins in 2006. Veteran Saints fullback Heath Evans went out last season with a torn ACL and the team signed Kyle Eckel, who didn’t last the season either.
