Per the Mothership, the Kansas City Chiefs re-signed starting center Rudy Niswanger to the restricted free agent tender and signed former Cowboys tight end Tony Curtis to a contract.  Terms of the deals were not announced.

The details on Curtis (no, not that Tony Curtis):

Curtis (6-5, 251) has seen action in 36 games during his three-year NFL career with Dallas (2006-08). He has caught 11 passes for 80 yards (4.5 avg.) with three TDs and registered five special teams tackles to go with three kickoff returns for 27 yards. He has also played in one postseason game. Curtis recorded 14 receptions for 112 yards and three TDs for the Cologne Centurions of NFL Europa in 2007. He originally entered the NFL as a rookie free agent with Dallas in 2005 and spent his first NFL campaign on the Cowboys practice squad.

Curtis appears to be the type of tight end that Kansas City will supposedly want for its new offense...big, can catch a few passes, but not a guy who's going to end up getting featured.  Curtis was undrafted out of Portland State in 2005 and was the third-stringer backing up Cowboys Pro Bowler Jason Witten and former Texas A&M player Martellus Bennett in 2008 (and Anthony Fasano before him in 2007 and 2006).  Probably not a guy who's ever going to be that great, but I suppose there's an outside chance he could surprise...all three guys ahead of him on the depth chart in Dallas were talented athletes, so there's at least a slim chance he's a better-than-average second-stringer on a different team.

Niswanger, of course, had a non-descript but acceptable season for the Chiefs in 2008, starting 15 games, and his return brings some continuity to a Chiefs o-line that had its moments in 2008.
