Grigorij was injured twice last season. He sustained a foot injury prior to the season and then about halfway through the season he broke the same foot again.
It wasn't a crash though but rather he got his foot somehow stuck between the ground and the footrest.
As far as his love life is going, he is married and have two kids.
Also I disagree about him being a gating tart, he is usually a very poor gater but is very good at finding lines to pass other riders however that requires
a track with more then one line which is why his results is usually very poor at tracks where gating is everything.
