Bad Ankle Contusion after hit by hockey stick

In the midst of an important hockey match, one of my players had a hard hit by the follow-through of the hockey stick by an opposing player. The burly defender hit the ground at an instant holding onto his ankle and the umpire immediately signalled me to run in to evacuate the player.

There was a large soft swelling (2cm X 3cm X 8cm) on the outer (lateral) aspect of his left ankle which looked really angry looking. He was carried out with 2-man carry and immediately examined on the bench. He was extremely lucky that it was just a soft tissue injury and the tendons and bone was spared.

We treated him with RICE treatment, NSAIDS medication and Arnica gel. He played in the finals yesterday despite having mild pain.
