Titans add Johnson to defensive line

The Tennessee Titans agreed to terms on a one-year contract with free agent defensive tackle Antonio Johnson on Monday.

Johnson, 28, was originally drafted by Tennesse in the fifth round of the 2007 NFL Draft, but injured his knee during rookie training camp and was placed on injured reserve.

He was placed on the team's practice squad for most of 2008 until the Colts scooped him up. Johnson went on to spend five seasons with Indianapolis, where he was a starter on the defensive line for the past two years.

In 67 career games, the Mississippi State product made 46 starts and has recorded 83 tackles with 1.5 sacks.

Tennessee also announced that they have waived rookie linebacker Tom Wort, who recently failed his physical.
