To be honest watching on TV the Zagar exclusion was plain wrong, however the Linback one was a tough one for the ref to call as the Pole had the drop on Linback and was a wheel ahead when he started turning into the corner, however then Linback still tried to force his way up the inside and there was elbow contact between the 2 and Linback lost control and took them both down.
Tbh having seen the replay a few times i think that Linback was correctly exluded as like in the SWC he was trying to force things to happen where a wiser head would have backed off. Maybe Linbacks reputation will give him problems now with refs and riders??
However seeing how poor the racing was at Wroclaw maybe Linback thought if he didnt get into the lead on the first turn he wouldnt be able to pass the Pole so thats why he tried to hoof the Pole out of the way.
