Passage: 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. Apart from the wicket-keeper, protection for the hand or fingers may be worn only with the consent of the umpires.Fielders are permitted to wear a helmet and face guard. This is usually employed in a position such as silly point or silly mid-wicket, where proximity to the batsman gives little time to avoid a shot directly at their head. Due to the discomfort and risk of being hit, the duty of fielding "under the helmet" or "under the lid" is often delegated to the most junior member of the team. If the helmet is only being used for overs from one end, it will be placed behind the wicketkeeper when not in use. Some grounds have purpose-built temporary storage in the form of a cavity beneath the pitch, approximately 1 m × 1 m × 1 m (3 ft 3 in × 3 ft 3 in × 3 ft 3 in) in size, accessed through a hatch flush with the grass, which can be used for storing a helmet, shin pads or drinks for the fielding side. 5 penalty runs are awarded to the batting side should the ball touch a fielder's headgear whilst it is not being worn unless the ball previously struck a batsman not attempting to hit or avoid the ball. This rule was introduced in the 19th century to prevent the unfair practice of a fielder using a hat (often a top hat) to take a catchAs cricket balls are hard and can travel at high speeds off the bat, protective equipment is recommended to prevent injury. There have been a few recorded deaths in cricket, but they are extremely rare, and not always related to fielding.
