Looks like 3 to 4 weeks and no exercise during that period just rest and IV fluids if needed. Sometimes recovery can be slow
( probably not for an elite athlete though imo)
RECOVERY
In most cases, the recovery period is 3-4 weeks, during which time the player rests the
abdomen. When the pain begins to subside, the doctor will take CT scans to assure that the
hematoma (a swelling filled with
blood as a result of the bruise) has subsided. It is vital that the athlete be kept out of competition long enough for the contusion to heal. If there is any question as to whether he is ready, he will not be cleared to play.
