"We have some very specific things that we'll be talking to the general managers about, seeking their input and hopefully ultimately their approval," NHL Commissioner Gary Bettman said after the Board of Governors met Wednesday.

Commissioner Bettman and NHL Deputy Commissioner Bill Daly declined to give specifics until after the GMs meet.

"There will be a lot of specificity tomorrow," Daly said. "We have specific rules. We just have to get the language."

The Competition Committee recommended changes to the coach's challenge and expanded video review, including as it relates to a referee's ability to review some of his own calls on the ice.

The Competition Committee also recommended:

-- A player be reasonably required to leave the ice if his helmet comes off during play.

-- The defending team not be allowed to change lines when a goalie freezes the puck on a shot from outside the red line. The attacking team would have the choice of end-zone dot for the face-off.

-- The attacking team have the choice of end zone dot on a face-off after an icing and starting a power play.

-- The defending team not be allowed to change lines and the attacking team have the choice of end-zone dot for the face-off, if an official determines a skater on the defending team knocks off the net unintentionally.

-- All face-offs be at one of the two dots in the attacking zone when the attacking team is responsible for the puck going out of play in the attacking zone.
