Two days after third-string quarterback Matt Blanchard suffered a broken knuckle on his left hand in a preseason win over the Chargers, the Bears on Saturday signed free agent Jordan Palmer.

Jordan Palmer

The younger brother of Cardinals quarterback Carson Palmer, Jordan Palmer has appeared in four NFL games over four seasons with the Bengals (2008-10) and Jaguars (2012), completing 10 of 15 passes for 59 yards with two interceptions and a 34.4 passer rating.

Palmer was selected by the Bengals in the sixth round of the 2007 draft out of UTEP. The 6-5, 232-pounder was waived as part of final cuts, but rejoined the team in 2008, appearing in three games and completing 7 of 12 passes for 41 yards with two interceptions and a 25.3 passer rating.

Palmer, 29, spent part of last season with the Jaguars, but did not appear in a game.

Blanchard was injured in the second half of Friday night's 33-28 preseason win over the Chargers at Soldier Field. In two preseason games the first-year pro from Wisconsin-Whitewater completed 16 of 19 passes for 192 yards with one interception and a team-high 86.8 passer rating.

The Bears on Saturday also signed defensive tackle Eric Foster and waived defensive lineman Jamaal Anderson and linebacker Andrew Starks.

Foster appeared in 49 games with 19 starts over four seasons with the Colts from 2008-11 after signing with Indianapolis as an undrafted free agent from Rutgers. The 6-2, 265-pounder recorded 117 tackles, six sacks, four pass breakups, three fumble recoveries and one forced fumble.
