Boss Warren Gatland indicated the lock would be punished for his ‘stupidity’ after England scored 17 points during his ten minutes in the bin during Wales’ 30-17 defeat.

But Jenkins maintains Jones’ indiscretion should be used as a wake-up call for the entire squad that discipline is key during every game.

And he believes the 24-year-old can come back stronger from the disappointment and set an example to the rest of the team going forward.

He said: “We’ve all made mistakes and Alun made one on the weekend.

“We’ve had other players in the past who have been sin-binned and we’ve come through it unscathed. On Saturday, we conceded some points.

“But it’s one of those things. We learn from it and we move on.

“Alun is a fantastic rugby player. He made a genuine mistake and we’ve got to accept that, deal with it, move on and make sure our discipline is fine come Saturday.

“We obviously want discipline to be at its utmost. When you play in these games, you want your 15 players on the field at all costs.

“If you don’t, you are going to suffer and concede points and we did on Saturday.

“Alun is hurting as much as anyone. He has just got to learn from it and put it right on Saturday.”
