The Stormers have signed Canadian loose forward Jebb Sinclair on a loan deal from Aviva Premiership side London Irish as loose forward cover.
With Burger, Vermeulen and Koster only due back after the June break, the Canadian International and London Irish player will bring experience and physical presence to the young Stormers loose forward contingent.
Sinclair will be available for the next 4 games for the Stormers, will then play for Canada in the June international window, returning to Cape Town for the Stormers remaining 3 league fixtures.
In terms of the Sanzar regulations he will not be eligible to play any knock-out games should the Stormers qualify.
Sinclair has 25 Canadian international caps (2008-2011), the last being the Rugby World Cup game against New Zealand in Wellington, on Oct 2, 2011.
Sinclair took up a contract with London Irish after the Rugby World Cup.
