The Titans announced the moves Wednesday.
The 6-foot-6, 305-pound Svitek has played 74 games in eight seasons, and he has been with Kansas City, Atlanta, New England and Cincinnati. He was with the Patriots last season where he played in 13 games with two starts at right tackle. A sixth-round draft pick in 2005 by Kansas City out of Stanford, Svitek has played both left and right tackle.
Svitek helps replace Michael Roos, who was placed on injured reserve last weekend.
Brackett was released Monday after playing Sunday against the Jaguars.
