Richmond forward Ty Vickery has received a four-week AFL ban for his strike on West Coast's Dean Cox, which left the retiring ruckman concussed.
Vickery was referred straight to the tribunal for striking Cox in last Friday night's match at Subiaco Oval after roundhouse punching Cox in the second quarter of the Tigers' 17-point win.
The punch saw the Eagles favourite slump to the ground before being substituted from the match because of concussion.
Vickery's advocate asked that the case be treated as a guilty plea and did not put forward any evidence, while the three-man tribunal panel was given a transcript of the player's public apology to Cox.
Both sides were content with a five week penalty being reduced to four weeks, with the tribunal handing down a 495-point penalty with 95 carryover points.
The jury took six minutes before agreeing on the penalty.
Tribunal chairman David Jones said the case was a serious one, but not one which resulted in any facial fractures.
"It does seem that it was a spur of the moment reaction to something that happened previously," Jones said.
"[Vickery] is contrite and remorseful in terms of his actions, and that seems to be very clear. That is genuine on his part."
