Wests Tigers pre-season squad increased on Monday with the return of Michael Chee Kam, Paul Momirovski and Robert Jennings after their representative commitments as well as Thomas Mikaele following the birth of his first child.

The quartet joined Wests Tigers extended training squad on the field at Concord Oval today for a range of tests and drills as pre-season training continues.

Jennings was due back later following his strong World Nines campaign with Tonga while Momirovski was given an extended break due to his representative debut for the Prime Minister's XIII against the Fiji Prime Minister's XIII.

Both outside backs returned without an issue and will join the full squad as usual, while Chee Kam will be monitored after picking up a minor shoulder injury playing for Samoa in the World Nines and their following Test matches.

The versatile forward will be a regular in team training with no surgery required, while Mikaele returned without an issue for his first day back on the job.

Chee Kam's Samoa teammate David Nofoaluma and the remainder of Wests Tigers NRL squad will return for pre-season training in early December with the only exception of five-eighth Benji Marshall, who is set for a later return following his extensive commitments with the New Zealand national side.
