New Zealand captain Brendon McCullum is set to miss his side's third one-day international against Sri Lanka due to a back injury.
McCullum hurt his back while fielding in the second ODI on Monday as New Zealand cruised to a 10-wicket win and 2-0 series lead.
He is struggling to recover in time for game three of the series in Nelson on Thursday as the hosts look to clinch the five-match series.
New Zealand coach Mike Hesson said the 34-year-old was likely to miss the encounter.
"He's still pretty sore. It's unlikely he'll play, but he's still a chance," he said.
"Normally we talk about 24 to 48 hours [to recover]. It's probably closer to 48 than 24. He's certainly improving but unless he's good to go, we won't risk him."
In some good news for New Zealand, star batsman Kane Williamson is close to a return from his knee injury, while paceman Adam Milne also looks set to play.
The Black Caps have dominated the opening two games of the series, winning the first ODI with 174 balls to spare and the second with 250 remaining.
Martin Guptill has made 172 runs, including an incredible unbeaten 93 off just 30 balls in the second ODI as he made the fast ever ODI half-century by a New Zealander.
Matt Henry has done most of the damage with the ball with eight wickets, setting up the hosts' two victories.
Sri Lanka have slumped to starts of 65-6 and 56-5 to be on the back foot from the outset in both games so far.
Captain Angelo Mathews is sure to demand better from his top-order and only improvement from his batsmen will see them test New Zealand.
