Ellis sprained his right knee in Miami in Week 7 and has not played the past four games. He has gone through all portions of practice this week, a team source tells NFL.com senior writer Steve Wyche, and Ellis could resume his starting position.
Ellis was not listed on the team's official injury report. Starting cornerback Jabari Greer also appears close to returning from his pulled left groin after practicing a second straight day on a limited basis.
