<div id="subtitle">Panthers RB Jonathan Stewart sidelined with heel injury; uncertain to play against Oakland</div><div><p>Carolina Panthers rookie running back Jonathan Stewart missed his second straight practice Thursday and was in a walking boot to protect his sore left heel.</p><p>Stewart first complained of the injury two weeks ago. He played in Carolina's win over Arizona on Oct. 26, but was held to 10 yards on eight carries.</p><p>The Panthers were off last week, but the injury has kept Stewart sidelined. His status for Sunday's game at Oakland is uncertain.</p><p>"It's a sharp pain in my heel," Stewart said. "I have to run the ball and it hurts every time I press off on it."</p><p>Stewart, Carolina's first-round pick, has been splitting carries with veteran DeAngelo Williams. Stewart has rushed for 362 yards and a team-best five touchdowns.</p><p>"It's day to day," coach John Fox said. "But any time you don't have a guy out there it's always a concern."</p><p>The Panthers had better news with their offensive line. Center Ryan Kalil and right tackle Jeff Otah practiced for a second straight day and are expected to start against the Raiders. Kalil has missed the past three game and Otah the past four with right ankle injuries.</p><p>Reserve defensive tackle Darwin Walker missed practice with a sore neck. Walker has not played or practiced since being in a car accident two blocks from Bank of America Stadium the day before the Cardinals game.</p><p>Walker said Thursday that a woman ran a red light and he T-boned her car. The impact totaled Walker's car.</p><p>"It was like a super-hard hit on the field," Walker said. "My neck still hasn't recovered."</p><img src="http://admatch-syndication.mochila.com/images/ad.gif?aid=36483544&bid=informcom" /></div><div id="copyright"><div>
