NASHVILLE, Tenn. - Chris Simms joined the Tennessee Titans' practice Wednesday after agreeing to terms to back up veteran Kerry Collins at least for one week while Vince Young's sprained left knee heals.

Simms spent the past five years with the Tampa Bay Buccaneers, starting 15 games of 19 games played. He led the Bucs to a playoff spot in 2005, throwing for 2,035 yards and 10 touchdowns.

He started the first three games of 2006 for Tampa Bay before getting hurt and having his spleen removed. He spent most of 2007 on injured reserve, and Tampa Bay waived him on Aug. 31.

"Chris has been a starter in the league and should fit into our system well,'' said Titans general manager Mike Reinfeldt. "He is a smart player who is a student of the game and has the presence in the huddle that you look for in a quarterback.''

The Titans waived tight end Dwayne Blakley and also added quarterback Preston Parsons to the practice squad to replace Ingle Martin, who signed with Kansas City. Parsons played at Northern Arizona and has been with Arizona and Denver in the NFL.
