The Chiefs have signed 26-year old QB Ingle Martin to the practice squad as he will serve as the #3 QB on the Chiefs until Brodie Croyle is ready to return.  He played in all 4 preseason games for the Titans this season and he completed 13 of 25 passes (52%) for 185 yards without a TD pass or a interception (76.2 QB Rating).  He also carried the ball 6 times for 18 yards (3.0 ypc).  Martin has only one game of NFL experience in 2006 with the Packers and all he did was kneel on the football 2 times for a loss of 5 yards.  This was a good signing for the Chiefs who had to protect themselves more at QB with Croyle out.
