what type of strapping and bandages do rugby players use before they go out on the field?

i want to know how the physios put the tape and bandages on the players because i want to be a physios when i grow up and for self purposes before matches like was it zinc oxide tape that bryan habana had on his legs in the 2nd test against the lions?

Generally, props and 2nd row players may have their heads taped to try and avoid ‘cauliflower ears’. As well as this, 2nd rows and flankers often have a sausage shaped piece of paper or fabric taped around their legs to aid the lifters in the line-out. Other than this, players generally only have parts of their body taped up if they are recovering from an injury, i.e. thumb, or wrist injury.

As for Habana, yes it was probably medical tape of some sort. He may have received a cut to his leg and the tape would be to stop the bleeding to avoid the need for a blood substitution, however I don’t know, only speculating.
