Graeme Smith is determined not to let a broken finger interrupt his cricket, the South African captain told Reuters on Wednesday.

Smith suffered a break to the middle finger of his right hand while attempting to take a catch off his own bowling on the final day of the Supersport Series match between Western Province and Gauteng at Newlands on Monday.

Although the finger is broken, Smith is expected to train with Western Province on Thursday. A decision on whether he is able to play for his province in a domestic one-day game on Friday will be taken later.

"I had a little bat this morning and it was very, very painful," Smith told Reuters by telephone.

"Tomorrow morning I'm going to have a local anaesthetic and I'll have a bat again to see if it works. If it does, I'll have another injection before Friday's game.

"Even if I get hit on it, it can't get any worse. It's not connected to anything," Smith said.

South African national team physiotherapist Shane Jabaar said the break was "an innocuous, undisplaced fracture and is not too serious."
