Titans mull Johnson, but go with Simms as backup QB

The Titans considered adding Doug Johnson to their quarterback depth chart this week to back up starter Kerry Collins, but instead will go with recently signed Chris Simms as the No. 2 quarterback against the Bengals, according to a source.

Johnson's familiarity with the Titans' offense under offensive coordinator Mike Heimerdinger, piqued the team's interest but in the end they decided against adding the veteran quarterback.

Johnson was with the Titans during the 2004 season when Heimerdinger was the team's offensive coordinator. Heimerdinger left the team in 2005 to become the New York Jets' offensive coordinator. The past two seasons he was an assistant with the Denver Broncos but returned to the Titans this season to run the team's offense.
