"Haddin is the incumbent and the place belongs to him. Paine knows that he got into the squad just because Haddin was injured," Nielsen said.
"We also cannot forget that Haddin was in great form with the bat before he was injured. Paine has done well in whatever opportunities he has received but, unfortunately, there is place for only one wicketkeeper in the squad," Nielsen added.
The 24-year-old Paine has scored a century and two half-centuries for Australia in 13 one-dayers and opened the innings.
However, the coach had some words of comfort for the young Tasmanian.
"Paine will have to wait for his chances like Haddin did when Gilly (Adam Gilchrist) was the wicketkeeper. What he has done with his good performance is that whenever there is a need for a wicketkeeper, he will be the first one to get an opportunity," Nielsen added.
Meanwhile, Paine insisted he is not thinking about the future and for now looking forward to have a good series against India before Haddin returns to the squad next month.
