FLOWERY BRANCH — The Atlanta Falcons have lost another defender with safety Kemal Ishmael getting placed on injured reserve. Coach Dan Quinn said Friday that Ishamel has played much of the season with an aching shoulder and decided this week to undergo season-ending surgery. The Falcons (8-5) host San Francisco (1-12) on Sunday and will be without All-Pro receiver Julio Jones for the second game because of a sprained toe.
