The decision was prompted by Shaun Tait's sudden withdrawal from cricket due to physical and mental stress.
''We are certainly conscious of the fact Brett has worked hard. We will need to sit down and choose a time (to rest him) which suits Brett and the team. It is important that he is fresh and going well,'' Nielsen said.
''His resilience has been outstanding, he is in such a great vein of form. That is why it is critical that we do give him a spell at some stage in order to increase his longevity for as long as possible,'' he added.
''He has played a massive part in our team, he has been brilliant for us all summer. He has bowled long spells, aggressive spells.'' According to Lee, he may get a rest after Australia's second match of the ongoing tri-series against Sri Lanka in Sydney on February 8.
''I have bowled a lot of balls this summer and my workload has increased a fair bit. We'll have to wait and see (about a rest). I'm looking forward to playing in Sydney in front of my home crowd, and we'll see what happens after that,'' he said.
