The Sharks have reassigned forward Freddie Hamilton to Worcester, the team announced on Friday. Hamilton, 21, is scoreless with a -1 rating in seven games with the Sharks this season. He was recalled on Dec. 8 and played in the previous three games. The move could indicate that forward Mike Brown is healthy. Brown has not played since Dec. 3 in Toronto, missing the last five games with a lower body injury. He was placed on injured reserve the same day Hamilton and Matt Nieto were recalled from Worcester.
