Rookie quarterback Tarvaris Jackson could be sidelined a few weeks after he injured his knee – believed to be cartilage damage to his right knee – Thursday in one of the final plays of practice.
"He got it banged once in college, not related to this I don't believe, but they'll probably have to clean up his knee on Monday and have a procedure, much along those same lines as Chuck Gordon," Vikings head coach Brad Childress said.
Charles Gordon, a rookie cornerback on the practice squad, injured his knee in training camp on Aug. 3, had surgery and made it back four weeks later in good enough shape to play in the Vikings' preseason finale Aug. 31 against Dallas and make the practice squad.
Childress said the timetable is approximately the same for Jackson.
"Some guys heal better than others. We just have to see. You never know until you go in and let the doctors see it," he said.
The injury happened when Jackson broke the pocket and stepped awkwardly, Childress said.
The Vikings could have another position player currently on their roster act as a backup behind Brad Johnson and Brooks Bollinger. Last week, Jackson was a game-day inactive, but could have been used as an emergency quarterback if both Johnson and Bollinger were knocked out of the game.
Childress declined to say which other position players might be in a position to fill that emergency quarterback role if the team doesn't sign a short-term, third-string quarterback.
J.T. O'Sullivan, who was with the Vikings part of last season and during the off-season, was released in the final roster cutdown on Sept. 2, along with Mike McMahon. O'Sullivan is currently on the New England Patriots' practice squad and could be signed to another team's active roster. However, the Patriots only have two active quarterbacks and could opt to sign him to their 53-man roster if they got wind of another team's interest.
McMahon remains unsigned.
Other top options available are former Vikings Todd Bouman and Jay Fiedler, Koy Detmer, Tommy Maddox, Vinny Testaverde, Tony Banks and Shane Matthews.
