IRVING, Texas --Fullback Tony Fiammetta again did not participate in Monday's walkthrough with an undisclosed illness that sidelined him against Washington and quite possibly could keep him out Thanksgiving Day against Miami.
Head coach Jason Garrett said the medical staff hasn't yet determined the origin of Fiammetta's symptoms, which include nausea when he works out. He was at Valley Ranch on Monday, and the team doesn't believe the illness is a long-term concern, Garrett said.
"I don't want to get too much into detail about that, but that's really been it more than anything else," Garrett said. "So we have to understand why, whether it's some illnesses in his family or whatever -- I don't want to go into too much detail. But we're just trying to get to the bottom of it and we're doing everything we can to do that."
Fiammetta has been a sturdy lead blocker since signing early in the season. Running backs DeMarco Murray and Felix Jones combined for 91 yards on 30 carries Sunday without Fiammetta in the lineup, though the Redskins also committed extra defenders to stopping the run at times.
Elsewhere on the roster, starting safety Gerald Sensabaugh has a walking boot on his injured right foot but sounded optimistic he could play Thursday. He came up limping in the second quarter against the Redskins but finished the game.
Garrett said backup quarterback Jon Kitna's sore back is "a tick more severe" than his previous issues in preseason. Kitna did not make the trip to Washington, and Stephen McGee will continue to be the primary backup for Tony Romo until Kitna returns.
