Clark handed No.6, Vlaar No.4 and Lowton requests No.34
James Collins relinquished it when he departed for West Ham this morning.
And Clark was quick to snap up the prestigious top made famous by Kent Nielsen, Dennis Mortimer and Gareth Barry.
New signing Ron Vlaar, who tied up a deal this afternoon, has been given the No.4 shirt, the same as he wore with Feyenoord.
Olof Mellberg, Gareth Southgate, Shaun Teale, Paul McGrath and Allan Evans are previous incumbents.
Matthew Lowton requested the No.34 shirt for sentimental reasons, as it was the first one he was ever given.
Karim El Ahmadi wears No.8, Brett Holman No.14 and Brad Guzan No.22.
Club captain Stan Petrov keeps the No.19 shirt.
