Hamill was recalled on an emergency basis Wednesday afternoon and will join the club for its morning skate on Thursday. He will be available if needed for that night's matchup with Edmonton at the Garden.
Hamill was the Bruins' first-round pick in 2007 (8th overall), but has played just four games in the NHL in his first three professional seasons. He managed two assists in those games, but has struggled to live up to the expectations of his high draft slot.
Hamill has gotten off to a strong start this season with the Bruins' American Hockey League affiliate in Providence, leading that club with 5-5-10 totals through 14 games.
The Bruins are in need of reinforcements with both Rich Peverley and Daniel Paille currently sidelined. Peverley returned to practice on Wednesday and could play on Thursday, but missed several practices last week and Monday's game against the Islanders with an undisclosed injury.
Paille was struck in the face with a shot on Monday and underwent surgery to fix his fractured nose on Wednesday. He is doubtful for Thursday's game. If both Peverley and Paille are out, Hamill will get a chance to play his first game of the season with the big club.
