Career
His regular position is flanker or number eight. Katzen played rugby for Wynberg Boys" High School, but was not selected to represent his provincial union Western Province at any youth tournaments. After high school, however, he joined the Western Province Rugby Institute.
In 2012, he played for Western Province U21 in the 2012 Under-21 Provincial Championship.
He made four appearances during the regular season of the competition, helping his side to finish in third spot on the log to earn a semi-final spot. He also made a crucial contribution in their final regular season match, scoring two tries in their 39–33 victory over Free State U21.
He made four appearances for the UCT Ikey Tigers in the 2013 Varsity Cup competition, scoring a try in their match against the Northwestern University Pukke. Overall, his team had a disappointing season, finishing second-bottom in the competition.
He was named the captain of the Western Province U21 side that played in the 2013 Under-21 Provincial Championship and started nine of their fourteen matches.
He scored tries against Leopards U21, Sharks U21 and Golden Lions U21 during the regular season, guiding his side to eleven wins in twelve matches. He started in an epic semi-final match, with Western Province U21 eventually winning the match 44–31 after extra time. He also started the final against Blue Bulls U21 and scored two tries in a man-of-the-match performance as his side ran out 30–23 winners to be crowned 2013 champions.
Katzen missed a few fixtures due to his involvement with the senior team
He again came on as a late replacement in their 29–27 victory over the Free State Cheetahs in Bloemfontein a week later and was named on the bench for the third consecutive time for a match against the Golden Lions in Cape Town, but wasn"t used in the home side"s 36–23 victory. Katzen picked up a shoulder injury that kept him out of the start of the 2014 season, but he recovered to make a single appearance in the 2014 Vodacom Cup, in a 14–23 defeat to the SWD Eagles in George.
However, he lasted just 12 minutes of that match before sustaining a serious knee injury that ruled him out for over a year.
