Just thought I would throw this out there. Noticed a coach at our club limping slightly. When I asked him about it..he said he got a turf burn on his knee that became really infected. He was now on antibiotics and crutches to take pressure off the knee and let it heal. I always see GKs at training sessions wearing shorts and short-sleeve shirts. Then in games they wear long pants/long-sleeve jerseys etc. I don't get it. You are working much harder during a training session I would presume. Goes back again to my comment on another thread.."train like you fight." My kid ALWAYS wears long pants/long sleeves even on the hottest days regardless if it's grass or turf. She doesn't want to be burned. She's had a few nasty ones over the years and that was because she didn't tell me she needed new pants and continued training on the worn out ones. It's a rare occasion that she switch to a short sleeve jersey. Might happen at a tournament where she's already played the same field and it's decent enough to make the switch but usually only based on how hot it might be as well.
