The New Zealand cricket coach Mike Hesson is playing down the severity of fast bowler Adam Milne's injury.
Milne got through seven overs in the four-wicket win over Sri Lanka in Nelson, before he suffered a side strain.
Initially Hesson didn't think it was too bad.
"It is one of those muscle injuries that you tend to have another re-think but hopefully we got it early enough. Like any quick bowler the old side injury is something you have to be a bit cautious of, so he could have carried on but we decided against it."
Milne didn't play the first of the two final ODIs in Dunedin this weekend.
