Cape Town - Western Province are sweating over the availability of fullback Cheslin Kolbe who injured his knee in their win over the EP Kings at Newlands on Friday night.Kolbe scored one of WP's seven tries as the Capetonians thumped the men from Port Elizabeth 49-14.However, coach Allister Coetzee revealed afterwards that Kolbe had injured his knee and they are hoping it's not too serious. Scrumhalf Nic Groom also injured his shoulder."We had a bit of a scare with Cheslin Kolbe's knee (he hyper-extended it) but we will see over the next 24-48 hours if there is any damage. Nic Groom took a knock to his shoulder late in the game, but, there too, we will have to see," Coetzee was quoted as saying on WP's official Facebook account.The coach was nevertheless happy with the performance as WP cemented their place atop the Currie Cup standings."I was pleased with our physical intensity. We got out the blocks quickly with three quick tries and I think we surprised them with that. Our set-piece, too, operated well and I was pleased with that (too)," said Coetzee.WP's next game is against the Golden Lions in Johannesburg next Saturday.
