We just don't know anything for sure. If he gets operated on, he's pretty much done. If he doesn't, it could be a one or two week problem.
Yahoo! player update thingy wrote:Nov 4 Conflicting information continues to pour in on the status of injured quarterback Byron Leftwich. Monday, Jaguars coach Jack Del Rio said Leftwich's left knee was "sore." Tuesday, it was reported that Leftwich has a sprained lateral collateral ligament that would not require surgery. Wednesday, Leftwich was on crutches with his leg in a brace and indicated there may be damage to more than one ligament. "Believe me, it's two different injuries," he told the Florida Times Union. After ruling out other possibilities, Leftwich declined to confirm an injury to the medial collateral ligament. "You know I'm smarter than that," he said, adding that he couldn't provide further information until his knee is re-examined Monday. A source close to Leftwich told the Times Union Leftwich may only miss two weeks—or one game, with the Jags on the bye this week. Del Rio said Brett Favre played with a brace following a bye week with a similar injury.
Views: Those with Leftwich on their squad are already prepping for the bye week without him, and they may need to make that replacement plan a little more long-term than they had hoped. Del Rio freely admits he keeps injury information close to the vest, so even following the exam on Monday we may not know exactly what's going on with Leftwich. There's no questioning the toughness of a guy who finished a game on a broken leg, with his linemen carrying him down the field following completions, but the Jags need to be concerned about their future as well as winning next week against the Lions. David Garrard has been working with the first team in practice this week and would step in if Leftwich is unable to play.
