 Another attacking placement on the leg side is the "leg side trap", which involves placing fielders near the boundary at deep square and backward square leg and bowling bouncers to try to induce the batsman to hook the ball into the air.For slower bowlers, the leg trap fieldsmen tend to be placed within 10–15 m from the bat behind square, to catch leg glances and sweeps.No member of the fielding side other than the wicket-keeper may wear gloves or external leg guards, though fielders (in particular players fielding near to the bat) may also wear shin protectors, groin protectors ('boxes') and chest protectors beneath their clothing.
