The Bears on Saturday signed three defensive players, including a former fourth-round pick.
With Brian Urlacher out for a week and Dom DeCicco sidelined, the Bears are thin at linebacker.
The Bears added linebackers Xavier Adibi and K.C. Asiodu, as well as defensive end Aston Whiteside. To make room for those players, the Bears waived defensive tackle Ronnie Cameron and cornerback Jeremy Ware and placed defensive end Alex Brown on the reserve/ retired list.
Adibi was a fourth round pick of the Houston Texans in the 2008 NFL Draft. He's appeared in 38 games with eight starts. Last season, he was with the Minnesota Vikings. He has 55 career tackles, forced two fumbles and also has a fumble recovery. He's also had 13 special teams tackles.
Asiodu has appeared in 11 NFL games with the St. Louis Rams and New Orleans Saints, racking up nine special teams tackles. He spent the 2011 preseason with the Green Bay Packers but was released before the regular season started.
Whiteside, who played at Abilene Christian University, was an undrafted free agent recently released by the Dallas Cowboys.
The Bears practice at 2 p.m. today.
