Wheater could also make his senior debut later this month as he is in the squad for the matches against USA and Trinidad and Tobago.
"To be named captain is a fantastic honour," said Wheater. "I didn't expect to be at Middlesbrough this season, I thought I may have been going out on loan, but the manager put me in and it's just gone on from there. I've got my Under-21s call-up and then the seniors."
Despite being an autograph-hunter, Wheater will not be asking his heroes for signatures when he meets up with the seniors.
