Franks, who sustained a mild concussion and back pain on a hit by Philadelphia's Brian Dawkins on Nov. 27, took the brunt of a collision with Chicago's Lance Briggs in the first series of the 19-7 loss Sunday. Coach Mike Sherman said Monday the initial diagnosis was Franks, who didn't play the remainder of the game, suffered neck and back injuries.
"The way he was torqued was a little bit different (from the Dawkins hit). It almost looked, when you look at it on tape and play it back, worse than (that) hit," Sherman said. "So his availability is very suspect at this present time."
-- Wide receiver Donald Driver sustained a hip pointer in the game Sunday and was experiencing swelling Monday.
Sherman said Driver probably will be held out of practice Wednesday.
Driver finished the game and led both teams with eight catches for 64 yards.
-- Defensive tackle Grady Jackson strained his hip, but was able to continue playing in the game.
-- Offensive right tackle Mark Tauscher strained his arch, aggravating the same foot that he hurt earlier in the season, but continued to play.
-- Robert Thomas, who missed the previous two games with a quadriceps injury, aggravated the injury but stayed in the game.
