a lot of wrestlers jog a few steps from the center of the mat to put there leg band on, slap there thighs, jump up and down, or whatever before the start of the match. other wrestlers kneel and close there eyes, most are praying but i think also some take a couple seconds just to try to clear there mind for the match. there are all kinds of routines which take 10 seconds before a match, if prayer is a problem then so is everything else. everyone should be able to do there own thing, a 10 second prayer doesnt hurt anyone.
