While the high-flying Rabbitohs ended up winning the match against the last-placed Bulldogs 32-24, the brain snap after the halftime siren had tongues wagging.
Lewis — the nephew of rugby league great Wally — appeared to be in a good mood as they walked from the field before the WWE move took things a little too far and saw him sent to the sin bin for his trouble.
“(Bulldogs coach) Trent Barrett must be absolutely filthy,” 2004 Premiership winner Braith Anasta said at halftime.
“It’s hard to explain why he did this.”
“That’s one of the craziest things I’ve seen in a long time,” added Panthers legend Greg Alexander.
After the game, Walker had no answers when asked why Lewis had tackled him to the turf.
“I wouldn’t have a clue,” Walker said with a laugh.
However, Walker may have had more of an idea than he first let on.
Lewis has played just four first grade games this season as well as five more in reserve grade, and Walker is believed to have hit him close to home.
