Hammers Mark Noble and Declan Rice were pictured being tested by West Ham medical staff as they arrived at Rush Green training ground yesterday afternoon.
This week two green tents appeared overnight in the car park of the West Ham training ground as the club prepares for project Restart as the Premier League prepare to play in June.
Rice and Noble had their temperatures taken and were asked to blow into a peak flow meter to measure lung capacity.
The peak flow meter is used by Asthmatics to measure their lung efficiency but can be used as an indication of other respiratory diseases.
All players are expected to medically screen and tested in the same way as they arrive in pairs individually at Rush Green
West Ham are not though to have virus testing capability as present but that is expected to follow soon with all players and staff tested twice weekly as part of new protocols.
