Carolina Hurricanes forward Jordan Staal sustained a concussion against the Florida Panthers on Sunday and has been placed on injured reserve.
There is no timetable for Staal's return, general manager Ron Francis told the News & Observer on Monday.
The Hurricanes recalled forward Phillip Di Giuseppe from Charlotte of the American Hockey League.
Staal, 28, left the game in the first period after taking a stick to the head from Florida defenseman Jason Demers. The Hurricanes defeated the Panthers 3-2 for their sixth win in eight games following a 3-6-4 start.
Staal has five goals and nine points in 21 games, and is averaging 18:28 of ice time, fourth among Hurricanes forwards. He signed a 10-year, $60 million contract with Carolina on July 1, 2012, after being acquired in a trade with the Pittsburgh Penguins nine days earlier.
