Most teams train on Astro turf I would imagine.
We played all our games on a grass pitch and our injury list through the season was:
Gary Sheehan
Stephen O Flynn
Dave Ryan
Brian O Callaghan
Shaun Maher
Shane Tracey
John Frost
David O Leary
Chris Breen
Thomas Lyons
James O Brien
Most of those where out for either most of the season of for weeks at a time so its not just playing matches on synthetic surfaces that picks up injuries. Luckily though we had some good A players to call upon when needed.
