Bills activate TE Shawn Nelson
The Bills (0-5) had until Monday to activate or release Nelson, who opened the season serving a four-game suspension for violating the NFL's substance abuse policy.
Ellis was the odd man out after failing to make the transition from defensive end to linebacker in the Bills' new 3-4 defense. The third-year player started the first two games this season, but was inactive in two of the past three.
