ST. JOSEPH, Mo. -- Newly signed running back Jamaal Charles and the Kansas City Chiefs make their 2014 training camp debut this afternoon. While we're waiting, let's update you on some bottom of the roster moves the Chiefs made this morning.

They signed two veterans, offensive tackle Ryan Harris and linebacker Josh Mauga. They released one rookie free agent, linebacker DeRon Furr, and placed another, running back James Baker, on the did not report to camp list.

The addition of Harris makes the most sense. The Chiefs aren't particularly deep at offensive tackle. Eric Fisher and Donald Stephenson are the starters. Veterans Jeff Linkenbach and J'Marcus Webb are the leading candidates to become the first tackle off the bench, so it wouldn't necessarily be a bad thing for the Chiefs if Harris wound up winning that job instead.
