To make room for Zavala on the roster, they released veteran running back/special teamer DeeJay Dallas. He started the year on the practice squad, played in a couple of games while Chuba Hubbard was injured, but was inactive the last two weeks.
The 27-year-old Moon, originally an undrafted free agent from Florida, has appeared in 21 games with two starts during his time with the Ravens and Steelers.
