Coach Marvin Lewis pronounced Green as "day to day" after the No. 1 receiver missed Wednesday's practice.
Other injuries we are tracking on Christmas Eve:
- T.Y. Hilton (hamstring) practiced for a second straight day. The wide receiver was limited during Wednesday's work out. Coach Chuck Pagano is hopeful that Hilton will play Sunday against the Tennessee Titans, but tight end Dwayne Allen (knee) will likely sit out. Pagano has vowed to play all of his healthy starters in the regular-season finale.
