The word bruise is an interesting medical term. Generally speaking a bruise, also known as a contusion, is a discoloration of the skin. Most bruises occur when blood vessels under the skin are damaged, but the resulting blood released is trapped under the skin. Bruises tend to be the result of blunt trauma but can be an indicator of a more serious underlying problem. The severity of a bruise is often downplayed, though that approach can be misleading depending on the type of tissue involved.
Most people associate the word bruise with the black and blue marks on the skin. Anybody that has stubbed a toe or walked into the corner of a table can relate. These types of injuries are usually just bruises that involve the skin. Muscle bruises or contusions can be more problematic as they involve damage to the muscle itself. Quadriceps contusions or deep thigh bruises are commonly reported in professional sports and can be very limiting. Bone bruises are even more significant and occur when the outer layer of bone tissue is cracked or broken. The body repairs bone bruises just like an outright fracture, creating new bone tissue at the injury site. Even nerve injuries can earn the bruise or contusion label.
Given the wide variety of possible outcomes, fantasy players shouldn't simply relax when the term bruise is used to describe the injuries of their favorite athletes. Instead, consider the specifics of each case to get a better idea of the context in
