The Kansas City Chiefs have a few offensive linemen missing so it caused them to do some mixing and matching at Monday afternoon's practice.

Guards Darryl Harris and Ryan Lilja sat out as did offensive tackle Barry Richardson.

With Lilja missing from the first team, the Chiefs slid Rudy Niswanger over to right guard. In place of Niswanger at center, they put Casey Wiegmann with the first team.

As Josh Looney of KCChiefs.com points out, Niswanger spent some time as a reserve guard with the Chiefs in 2007. He also started at least one game along every spot on the offensive line for LSU.

Jon Asamoah was banged up in the Atlanta Falcons game so maybe that's why Niswanger got the nod over him.

There's no word of a Lilja injury. My guess would be that it's just a veteran getting a day off.
