The Chicago Bears re-signed safety Derrick Martin and center Taylor Boggs on Monday.
Martin played seven games last season. He signed with the Bears after cornerback Charles Tillman's season-ending triceps injury. Martin mainly played on special teams.
Boggs played just one game for the Bears last year. He was set to be an exclusive rights free agent before re-signing. He could compete for the starting center spot if Roberto Garza leaves via free agency, but is more likely to be a backup.
