Orchard Park, NY (SportsNetwork.com) - Buffalo Bills quarterback Thad Lewis was held out of Wednesday's practice with a rib injury and is uncertain to be available for the team's upcoming game against Kansas City.
Lewis, who has started Buffalo's last three contests in place of a still- injured E.J. Manuel, bruised his ribs on the opening play from scrimmage in Sunday's 35-17 loss at New Orleans. The journeyman signal-caller did remain in the game, however, and completed 22-of-39 passes for 234 yards with one touchdown and an interception.
Head coach Doug Marrone told reporters that Lewis is "50-50" to practice on Thursday. Rookie Jeff Tuel and veteran Matt Flynn each received reps with the first-team offense on Wednesday with Lewis sidelined.
Manuel, who sprained the lateral collateral ligament in his right knee at Cleveland on Oct. 3, is not expected to return until the Bills' Week 12 bye at the earliest.
Lewis has performed capably since being elevated from the practice squad into a starting role, with the undrafted Duke product having completed 60.2 percent of his passes for 652 yards and three touchdowns with two interceptions over his three starts.
Two other key offensive contributors, running back Fred Jackson (knee) and wide receiver Stevie Johnson (hip), also did not participate in Wednesday's session.
On a positive note, running back C.J. Spiller was a limited participant on Wednesday. The fourth-year speedster was inactive for the New Orleans game due to a sprained ankle.
