Brian Urlacher returned to Bears training camp, but he didn't practice with his teammates at Bears training camp.
Excused for personal reasons for a week, including Thursday night's preseason opener against the Denver Broncos, Urlacher returned to Olivet Nazarene University on Saturday and rejoined his teammates. Urlacher, who hasn't practiced since July 31, didn't speak to reporters after practice.
In addition, Bears coach Lovie Smith did not provide a timetable for his return.
"Brian Urlacher is back, after he's taken care of some business," Smith said. "It's good to get him back on the practice field, even though he isn't practicing yet. He still has some soreness with the knee. We'll continue to monitor it.
"Exactly when he'll be back, I can't tell you that."
The Bears, though, are thin at the position.
Roach is currently filling in for Urlacher but young backup Dom DeCicco pulled his groin muscle and will be on the "shelf for a while," Smith said.
The Bears signed linebackers Xavier Adibi and K.C. Asiodu on Saturday, 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.
