The Bears signed veteran backup quarterback Jordan Palmer to -- at least temporarily -- replace No. 3 signal-caller Matt Blanchard, who was injured Thursday night in the 33-28 victory over the Chargers.
Blanchard suffered a fractured knuckle on his left (non-throwing) hand and will be sidelined for a still-undetermined time.
Palmer, the younger brother of Arizona Cardinals quarterback Carson Palmer, played in four games for the Bengals as a backup to his brother from 2008-10.
He completed 10 of 15 passes for 49 yards and 2 interceptions. The 6-foot-5, 230-pound Palmer was originally selected by the Redskins in the sixth round (205th overall) in 2007 out of Texas-El Paso. Palmer spent part of the 2012 season with the Jaguars but did not appear in a game.
The Bears also signed defensive tackle Eric Foster and waived defensive lineman Jamaal Anderson and linebacker Andrew Starks. The 6-foot-2, 265-pound Foster played in 49 games and started 19 times in four seasons (2008-11) with the Colts. He had 117 tackles and 6 sacks.
