Shaun Johnson ruled out giving evidence against Kevin Proctor after the Gold Coast Titans captain was sent off for allegedly biting him during a 30-18 win for Cronulla Sharks.

Proctor's 250th NRL appearance will not be remembered for the right reasons, as the forward was given his marching orders following an incident in the second half at Netstrata Jubilee Stadium on Saturday.

It was deemed after referee Henry Perenara asked the Bunker to examine footage that Proctor sunk his teeth into the arm of his New Zealand team-mate, so the 31-year-old was the first NRL player to be dismissed for biting.

Johnson, who came off with a groin injury later in the game, told Fox Sports: "Nothing happened, let's just leave it at that. We were both heated in the middle of the game and I was a bit high on him and whatever happened, happened, but we're still mates.

"It's his 250th [NRL match] and I don't want this to dampen this at all. He's been a great player for so long at Melbourne [Storm] and now Gold Coast, and he's led with his actions his whole career.

"I don't think it's appropriate and I guess this doesn't do Kevvie justice to talk about this. He's a great player and I've loved playing with him at Kiwi level and I've got nothing but respect for him."

Asked if he would testify against Proctor, Johnson replied: "No, not at all. I don't see the value of taking it any further than what's happened here today. I love him as a player and person, and I've got nothing more to say about it."

Three tries in the space of six minutes from Sione Katoa, Wade Graham and Jack Williams following Proctor's exit put the Sharks well on their way to a seventh win in nine matches.

Adam Reynolds was on target with a late penalty and a field goal after Alex Johnston grabbed a double in a dramatic 31-30 win for South Sydney Rabbitohs over North Queensland Cowboys.

Canberra Raiders put the sorry Brisbane Broncos to the sword in the final match of the day, Nick Cotric touching down twice in a 36-8 rout at GIO Stadium.
