The Bears will sign veteran safety Glenn Earl to a one-year contract, a league source said.
The Naperville North and Notre Dame product was invited to participate in the three-day minicamp this week on a tryout basis and showed enough to stick around.
Earl took a physical on Thursday and the Bears were convinced he is fully healthy. The Texans drafted Dominique Barber at safety last year and counted on him in phasing out Earl, who had missed the 2007 season with a torn Lisfranc ligament. The injury was suffered when he was run over by Cedric Benson in a preseason game at Reliant Stadium.
