Markshausen should sound familiar because, well, you really don't forget a name like that, but also because he went to training camp with the Chiefs this year. He made it to the final cut down with the team. He's listed at 5'11" and 185 pounds.
Interesting timing because Markshausen went to training camp with the Bears in 2010.
Bruggeman could be familiar if you've been paying attention. The Chiefs worked him out earlier this year in September (but didn't sign him). He's listed at 6'4" and 286 pounds as a center and originally entered the league as an undrafted free agent with the Tampa Bay Buccaneers. He played at Iowa under Kirk Ferentz.
The Chiefs had a couple of open spots on the practice squad from Jeremy Horne moving to the active roster upon Matt Cassel's trip to IR and David Mims movin' on up after Jared Gaither was released on Tuesday.
