KANSAS CITY, Mo. — Starting left guard Robert Gallery suffered a fractured left fibula and is expected to miss a month or so, based on the initial diagnosis.
Gallery left Sunday's game against Kansas City at the two-minute warning in the fourth quarter, though he first suffered the injury earlier in the game.
"I cracked back on a guy, and I heard it break," Gallery said. "I just have to get it fixed and come back as soon as I can."
Coach Tom Cable said Gallery's injury appears along the lines of the broken left ankle sustained by offensive tackle Khalif Barnes early in training camp. Barnes missed a little more than a month.
Chris Morris replaced Gallery at left guard, with Samson Satele taking over for Morris at center.
He jumped a Matt Cassel pass for tight end Sean Ryan in the third quarter, snared the ball and returned it to the Chiefs 49-yard line. The Raiders parlayed that into a tiebreaking field goal by Sebastian Janikowski from 54 yards.
On the second play of the fourth quarter, Huff reacted well to a seam pass to running back Dantrell Savage and made a lunging grab of an overthrown pass at the Raiders 6.
He also broke up a pass on a fourth-and-four play to seal Oakland's victory with 32 seconds left.
Huff credited All-Pro cornerback Nnamdi Asomugha with helping him elevate his play.
Huff is playing mostly in passing situations as the nickel back. He leads the NFL with three interceptions. He recorded only one pick in his first three seasons.
Their full-fledged commitment to Russell showed Sunday as Cable stuck with his quarterback despite few positive signs for the first 57 minutes, 22 seconds of the game.
"I really didn't," Cable said, when asked if he contemplated turning to backup Bruce Gradkowski. "It did not cross my mind."
Russell rewarded Cable's patience and confidence by leading the Raiders on a game-winning drive. He completed 4 of 7 passes for 67 yards on the pivotal possession.
"Never," Russell said about worrying about his job security. "I know that I am the guy."
Russell finished 7-of-24 for 109 yards and no touchdowns. He became only the second quarterback since the start of the 1997 season to win a game in which he attempted at least 20 passes and completed fewer than 30 percent.
Carolina's Jake Delhomme pulled off the feat in a 17-6 win over the Raiders last season, when he went 7-for-27.
