In his absence, Edinburgh, who are currently fourth in Conference B, will be looking to build on their 37-7 win against Southern Kings in their last Guinness PRO14 fixture.
Kinghorn has made five appearances for Scotland Under-20s, scoring 22 points, and will now be looking to make his mark in senior international rugby.
Ulster scrum-half John Cooney is another to have lit up the Guinness PRO14 this year, registering six assists and two tries for an impressive 87 fantasy points.
His six-point contribution with the boot proved vital in helping Ulster overcome Munster 24-17 last month.
Ulster sit third in Conference B ahead of Friday’s match against Southern Kings, with the South African side set to play in Belfast for the first time in their history.
Cooney will again be key for the hosts in this historic game.
Munster lock Jean Kleyn has the honour of being the most selected lock in Fantasy Rugby and has accumulated 66 points thanks to his four tries and a string of consistent performances.
Currently second in Conference A, Munster will be looking to maintain pressure on top side Edinburgh when they take on Zebre, who are currently bottom of Conference A with just three wins from their 13 fixtures so far this season.
