DENVER -- Danny Kanell missed Friday's practice with the flu, leaving the Denver Broncos with just one healthy quarterback for Sunday's game at Baltimore.
Newly re-signed quarterback Jarious Jackson took all the snaps during the Friday workout -- and he said he was coming down with a cold. Kanell, who was vomiting and experiencing other symptoms of the flu, was given intravenous fluids.
Kanell was listed as probable on the injury report, though coach Mike Shanahan said it was uncertain if he would be available Sunday.
"We'll wait and see," Shanahan said. "I really don't know. We'll see how he is in a couple of days. He's a little bit dehydrated. We gave him some IVs, and hopefully he'll be all right by game time."
The Broncos are extremely short-handed at quarterback: Starter Jake Plummer is out with a broken left foot and backup Steve Beuerlein was placed on injured reserve this week after breaking the pinkie finger on his throwing hand in Sunday's loss at Minnesota.
Kanell, the third-string quarterback, replaced the injured Beuerlein against the Vikings and was expected to start the next two games until Plummer returned. The Broncos signed Jackson on Wednesday as Kanell's backup.
Wide receiver Rod Smith is Denver's emergency quarterback.
Jackson was cut by the team two months ago. In his previous three seasons in Denver, he played in four games, completing 7 of 13 passes.
Jackson said he is taking medicine to try to reduce the discomfort of an oncoming cold.
Jackson said offensive coordinator Gary Kubiak jokingly told the players "to go lock ourselves up tonight. I think that's the plan for the majority of players, at least the quarterbacks. Hopefully we can give Danny something to get him healthy."
Although Kanell and Jackson both have had limited work with the offense, Jackson said, "I think both of us are ready. I think we have a good game plan going into this game, and it's going to be a dogfight."
