With all-rounder Hardik Pandya's anticipated return getting delayed after he failed the fitness test, India's limited overs squads are unlikely to be tinkered with much for the upcoming six-week tour of New Zealand.

Starting January 24, India will be playing five T20 Internationals, three ODIs and two Test matches, and squads for the tour will be picked on Sunday.

Pandya was expected to make the Indian squad after remaining out of action for four months due to a back injury but the all-rounder could not clear the mandatory fitness test, indicating that it will take him more to recover from the surgery he recently had.

India will be playing eight white ball games in New Zealand, and it will be interesting to see if the selectors pick a 16 or 17-member squad, instead of 15.

Pandya was also pulled out of the India A team's tour of New Zealand on Saturday after he failed mandatory fitness tests in Mumbai. The selectors had picked him in the squad without testing him in the Ranji games.

Tamil Nadu captain Vijay Shankar has been drafted into the India A team and he has already boarded the flight to New Zealand where they will play two 50-over warm-up games, three List A games and two four-day 'Tests' against the home A team.

With the India A team's shadow tour coinciding with the seniors' visit, it gives the selectors an option to draft players on SOS basis if the need arises.

The selectors will primarily focus on zeroing in on the core for white ball cricket considering that this is a T20 World Cup year.

While the T20 squad that played against Sri Lanka in the just-concluded series all but picks itself, Pandya was expected to be included once he proved his fitness in the warm-up games. However his failure to clear the fitness test is an indication that he is far from ready for interests.

It will be interesting to note if the ODI team is an extension of the T20 squad.

The weakest link in the ODI team is Kedar Jadhav, who has managed to hold onto his 50 over slot amid pressure to replace him.

In New Zealand, Jadhav's technical frailties could be exposed and his lack of overs in recent times makes him a case for exclusion.

In case the Indian team looks for technical solidity, Ajinkya Rahane could make a comeback, but if the team management is thinking in terms of treating 50 over games as an extension of T20 series, Mumbai player Suryakumar Yadav's explosive power hitting at No. 5 or 6 could be an option.

Both Surya and Sanju Samson are in the A squad.

The Test squad wears a very settled look with the only contention being the third opener's slot.

Picked as a reserve for the home series, the young Shubman Gill deserves to be the third opener, but K L Rahul's current form and experience in Test cricket could also be considered.

The selectors will also deliberate on if a third spinner (Kuldeep Yadav) is needed for the two-match Test series instead of a fifth pacer (Navdeep Saini) to accompany Jasprit Bumrah, Umesh Yadav, Mohammed Shami and Ishant Sharma.

The rest automatically pick themselves in case there are no fitness issues.
