Yeah! UEFA allow artificial pitches - except for the final. That actually happened a few seasons ago when the Champions League final was played in a stadium in Moscow which had an artificial pitch. It had to be replaced, with a grass pitch for the purpose of one game!
Regarding injury statistics, there have been studies done on this and the results seem to be consistent.
Generally, injuries were more prevalent on the old style AstroTurf, 1G and 2G pitches, than on grass.
But, since the advent of the modern 3G and 4G surfaces, there is no evidence that they cause any more injuries than grass. However, it was noted that there is obviously no data for 'long term' effects on players from always playing on these surfaces.
Yet, I'm sure some players find it more physically demanding to play on artificial surfaces and often players nursing ankle, back or knee injuries are often reluctant to play on the perceived harder surface.
Interesting times ahead, if the club are indeed looking seriously into this option. I'd be fascinated to hear Dougal's opinion as I remember he was quite 'outspoken' about this earlier this season - hoping Hamilton and Kilmarnock would be relegated!
