Professional career
Kansas City Chiefs
Medlock was drafted in the fifth round of the 2007 NFL draft by the Kansas City Chiefs with the 160th overall pick. Medlock was thought to go into the preseason competing with Lawrence Tynes for the kicking job, but the Chiefs traded Tynes to the New York Giants, thus making Medlock the de factostarter. Medlock was inconsistent in the preseason, making 3 of 6 kicks; the Chiefs released Medlock on September 10, 2007, after he converted a 27-yard field goal and missed on a 30-yard attempt in against the Houston Texans, and signed Dave Rayner as a replacement.

Toronto Argonauts

At the end of training camp, the Argos elected to keep both kickers and coach Bart Andrus elected to start Johnson for game one and placed Medlock on the practice roster. Johnson, however, was injured on the opening kickoff when he separated his shoulder when tackling the return man and Medlock was slated to kick for game two of the 2009 Toronto Argonauts season. On August 14, 2009, Medlock scored seven field goals, tying Lance Chomyc's Argonauts single-game team record and just short of the league record of eight shared by Dave Ridgway, Mark McLoughlin, and Paul Osbaldiston.
