Steelers not saying how long QB Dixon will be out

The Pittsburgh Steelers aren’t saying yet how long quarterback

Dennis Dixon will be out with a left knee injury, a problem that

typically sidelines a player for multiple games.

Dixon, who started the first two games of the season for the

suspended Ben Roethlisberger, was examined by doctors Monday and

might have additional tests Tuesday. Dixon, who injured the same

knee at Oregon in 2007, might not return before Roethlisberger’s

four-game suspension ends.

Charlie Batch, No. 4 on the depth chart, finished up after Dixon

was hurt Sunday during a 19-11 victory at Tennessee. He is

currently the only healthy quarterback on the roster.

Byron Leftwich could start against Tampa Bay on Sunday, but he

hasn’t played since spraining his left knee during a Sept. 2

exhibition game.
