New Zealand skipper Brendon McCullum is an unlikely starter for the third ODI against Sri Lanka at Saxton Oval tomorrow.
McCullum damaged a disc in his back diving for a ball on the boundary in Monday's match at Christchurch's Hagley Oval. He didn't bat later that day and did not train today.
A joint has flared more than expected, and the travel, and sitting on aeroplanes hasn't helped.
''He's still pretty sore," coach Mike Hesson said. ''It's unlikely he'll play but he's still a chance.
''Normally we talk about 24 to 48 hours. It's probably closer to 48 than 24. He's certainly improving but unless he's good to go we won't risk him. He's certainly one of those guys that if there's a chance he can play he'd like to."
