The CFL video replay policy is still under review.
"We haven't come to a firm conclusion yet," said Edmonton Eskimos head coach Danny Maciocia. "It seems that it's something that will be implemented. As far as all the details regarding it go, they are still unanswered."
Video review is one of the hot-topic items being discussed at the annual CFL meetings.
"The format obviously is extremely important," Maciocia said. "You want a format that already has been proven and it has been in the NFL.
"You want something that is as close as possible to what they're doing because they've gone through the growing pains with that system.
"We don't want to have a system in place where there are more questions than answers."
In the NFL, teams are allowed to challenge questionable calls throughout the course of the game. However if they lose a challenge, teams concede a timeout.
In the NFL teams have three timeouts per half. In the CFL they only have two.
"Games in the NFL go three-and-a-half hours," Maciocia said.
"Our game goes basically three hours.
"I'm all for instant replay, but we need a format or a system in place where we're going to help out the officials.
"It's also going to give us an opportunity to know when to challenge and when not to challenge."
