He was signed with the Houston Texans on July 28, 2011 as an undrafted free agent.

On November 15, 2012, Hartmann sued the county agency that operates Reliant Stadium, blaming "unsafe turf" for a possibly career-ending knee injury.

[2] Hartmann was released during pre-season cutdowns, and as a free agent, his suspension was extended by eight more games on September 24, 2012.
