Dodgers outfield prospect Alfredo Silverio, who had a breakout season in Double A Chattanooga last year, was involved in a significant car accident in the Dominican Republic on January 23. Silverio suffered injuries to his back, shoulder, elbow, and neck, but is also still suffering concussion symptoms nearly six weeks after the accident. There is no timetable for his return to baseball activities, let alone playing in games.

Silvero, who turns 25 in May, hit .306/.340/.542 with 42 doubles, 18 triples, and 16 home runs in Double A in 2011, and was added to the 40-man roster in November. He hit a home run in the Futures Game last July at Chase Field in Arizona. Silverio was voted by True Blue LA readers as the 13th best prospect in the Dodgers system, and tabbed by Brandon Lennox as the 12th best prospect in the system.

"I feel terrible for this kid," manager Don Mattingly said on Saturday. "You see his face and he looks dejected. He gets on the 40-man roster after having a really solid year last year and has this happen."

Mattingly said Silverio will likely remain at Camelback Ranch in Arizona once camp breaks, to continue to receive treatment until he is ready to get back on the field.
