"How many times do you see and how many times have strikers and goalkeepers collided? Nine times out of 10, it's just a collision where the striker falls over the goalkeeper and nothing happens.
"It's part of the game, sometimes these things happen and nobody goes into games with the intention to cause harm."
Warning: Graphic footage
Smeltz has had his fair share of nasty collisions, including a nasty gash suffered in the 2012 grand final, which required 55 stitches.
While that experience was painful, Smeltz said it hurt him more to have inflicted such an injury on a player he calls a friend.
"I've been on the end of this and as painful and unfortunate as it is, it's harder to be on this side because I caused it," he said.
The 34-year-old was not carded for the incident but could still find himself sanctioned by the A-League Match Review Panel.
Furious Newcastle coach Scott Miller has called for greater protection for goalkeepers and described Smeltz's tackle as "outrageous", "disrespectful" and "reckless".
It was a collision not too dissimilar to when the ex-Gold Coast United striker left another former Jets gloveman, Neil Young, with five fractures in his nose in 2010.
"If you look at his mouth, for me, that's not on," Miller said after the match.
"Irrespective if its a mistake or unintentional, it's not right. (It) is not only disrespectful, but slightly out of order, if someone requires surgery post a one-on-one with a goalkeeper."
