Ravens Pro Bowl DT Nnamdi Madubuike was a full participant in Wednesday's practice, which could signify that he will return to the field on Sunday against the Cowboys. Madubuike, who had been limited in practice the first two weeks, hasn't played in a year because of a neck injury. ILB Teddye Buchanan (knee) also had his first full practice of the year, too. Three starters didn't practice due to injury: WR Zay Flowers (hamstring), OLB Trey Hendrickson (finger) and OT Ronnie Stanley (toe).
