...the penalty would be the results of the matches he took part in being overturned and declared 28-0 wins for the opposition with a try bonus point awarded.
The table finished
Georgia - 44
Spain - 29
Romania - 28
Portugal - 26
Russia - 10
Netherlands - 4
So... Based on the earlier suggestion that the "Spanish" player only played in their 2 BP wins against the Netherlands, Spain drop to 19 and NL 14. Depending on the outcome with Romania and which games were impacted, then Romania could drop to below NL, enough for NL to nick the European playoff spot behind Portugal (with Russia disqualified), having accrued a potential 24 points as follows:
Cancelled match vs Russia - 4 points
2 defaulted matches vs Spain - 10 points
2 defaulted matches vs Romania - 10 points
And an actual playing record of played 9, lost 9, points for 98, points against 464.
