Buffalo Bills head coach Doug Marrone has confirmed that quarterback Thaddeus Lewis is a doubt for Sunday's match against the unbeaten Kansas City Chiefs.
Lewis was injured on the first play of his side's 35-17 defeat to the New Orleans Saints at the weekend but returned for the next series and played through the pain for the remainder of the match.
However, the 25-year-old was unable to practice today and is rated at "50-50" by Marrone for Sunday's match.
"The doctors call it a contusion. In layman's terms, I call it sore," Marrone told reporters.
