Silverio, considered one of the organization's better outfield prospects a year ago, was seriously injured in a January auto accident in his native Dominican Republic and missed the entire 2012 season.
Silverio suffered a serious concussion and other injuries, eventually undergoing Tommy John surgery on his right (throwing) elbow in May.
Silverio, 24, was coming off a breakthrough Double-A season in his eighth professional year, which included four seasons in the Dominican Rookie League. The slow bloomer hit .306 with 16 homers, 85 RBIs, 90 runs, and was added to the 40-man roster last November to protect him from the Rule 5 Draft.
With players that have declared free agency and the reinstatement of players that finished the season on the 60-day disabled list, the Dodgers roster now counts 36.
