The CFL has approved making pass interference subject to video review for the upcoming season.
Coaches are now allowed to challenge both called and potential defensive pass interference fouls under certain conditions.
"We are constantly looking for ways to make our great game even better and I believe we have done that today with the approval of this rule change," said CFL Commissioner Mark Cohon. "Being progressive and using technology to compliment the excellent work our officials already do on the field is positive for our teams, players, and ultimately, our fans."
The new rule now provides a team with the ability to use coaches' challenges to review a called or potential pass interference foul up to the final three minutes of a game. In the final three minutes and overtime, a team can only challenge such a call or non-call once, and only if it still has an unused challenge and a timeout remaining.
A coach must challenge to trigger a video review of a pass interference call or a potential pass interference call. They will not be subject to automatic review by the Command Centre.
An unsuccessful challenge of a potential pass interference foul in the final three minutes will result in the loss of a timeout. An unsuccessful challenge of an actual pass interference call in the final minutes will not result in the loss of a timeout.
The CFL is the first football league to subject pass interference to video review.
The role of the Command Centre has also been expanded to automatically review specific turnovers of fumbles lost and interceptions, and can now detect illegal participation fouls during a play (when a player returns to the field after voluntarily leaving it).
"We are very much looking forward to implementing the rule changes for the 2014 season now that we have received final approval from our Board," said Glen Johnson, CFL Vice President of Officiating. "We went through a very rigorous and inclusive process this off-season and we strongly believe that all of these rule changes will have a positive impact on our game."
Other approved rule changes to further protect the health and safety of CFL players include:
• Eliminating low blocks below the waist, other than those delivered to the front plane of a player, in all areas of the field except in the area between the tackles and two yards on either side of the line of scrimmage.
• Outlawing peel back blocks, which occur when a play changes direction in the backfield, forcing the defender to modify his pursuit, making him susceptible to blind low blocks executed by an offensive player moving toward his own end zone.
• Clarifying the rules that make it illegal to "deliver a blow" to an opponent's neck or head, and when it is illegal for a player to use their helmet to hit an opponent, standards already followed by officials but not yet codified in the rule book.
• Requiring an injured player to leave the field for three plays regardless of whether a penalty was called on the action leading to the injury (players currently have the option to stay in the game if a penalty was called on the play.)
Other approved changes to promote scoring and improve the flow of the game include:
• Allowing quarterbacks for each team to use their own team supplied Wilson footballs, provided they have met the "new ball" quality standard established by the league.
• Allowing centres to bob their heads multiple times in an effort to signal timing of the snap of the ball (to be used by visiting teams coping with noise in stadium).
• Allowing offences to further dictate the pace of play by no longer requiring the Head Referee to hold the 20 second clock for the defence to substitute.
