"Andre has four years of valuable experience on the NFL level," general manager A.J. Smith said in a statement. "He's healthy now and looking for a second chance. I'm excited to see what he can do."
Lott cracked the Washington Redskins' starting lineup for three games in 2004 before suffering a season-ending pectoral injury against Green Bay on Oct. 31. Last year, Lott suffered a knee injury during an offseason practice. He reached an injury settlement and was released by the Redskins before the season.
Lott has started three of 31 career games.
Lott was a fifth-round draft choice of the Redskins in 2002. He played in all 16 games as a rookie and was fifth on the team with 13 special teams tackles. In 2003, Lott played in 11 games and had six stops on special teams.
