>>Bears Sign QB McCown

The Chicago Bears have signed veteran backup quarterback Josh McCown with Jay Cutler's status for this week uncertain.

Cutler sat out the second half of Sunday's loss to Houston with a concussion. Jason Campbell took over and is expected to start Monday at San Francisco if Cutler can't go. But the Bears needed a backup.

McCown appeared in three games with Chicago last season and made two starts, completing 35 of 55 passes for 414 yards, two touchdowns and four interceptions.

The Bears also waived tight end Brody Eldridge on Tuesday.

>>Bears' Tillman's Wife Has 4th Child

Chicago Bears cornerback Charles Tillman's wife gave birth to the couple's fourth child. They were expecting a girl.

Tillman thanked his Twitter followers for their "thoughts and prayers" and added "Wife and baby are doing great" in a post Tuesday.

Tillman's status for Sunday's game against Houston was in question after he told a Chicago radio station he might have to miss it. He later said he expected to be available and wound up playing in a loss to Houston.
