Taping games for coaches to analyse for training purposes is a practice several of the Tasman Tanning Premier teams have adopted.
"It's a first that we've had a video [at judiciary]," said WRFU club liaison officer Paul Kenny, who saw the incident from the announcer's booth at Spriggens.
"It's usually used for coaching mechanisms, that's the purpose of it.
"If they know that video evidence is in play now, it's a hope that will deter them."
Kenny said as the WRFU was trying to get on top of ill-discipline and having video evidence on hand was a valuable tool, as it was in Super 15 and international rugby.
"Since they've introduced it in Taranaki [club rugby] ... red cards have been nil. If you do have any video evidence it would be good. We just have to have it in by a certain time." There have been 12 red and 64 yellow cards issued across all grades of Wanganui rugby this year.
