DOB: 19 May 1947
From: St. Patrick's College East Melbourne/University Blacks
Number: 23 1969-1972
A doctor off the field, he kicked five goals to help the Demons win the 1972 Reserves Qualifying Final, including three in the last term. His medical commitments often clashed with football, leaving him to arrive at games on little, or in some cases no sleep.
In his senior games, Sinclair was often used as a reserve. By the start of 1972 he'd started 12 games and been on the bench 14 times - including eight in 1971. He also battled injuries including two broken ribs, a broken hand, four torn hamstrings and a bout of glandular fever.
His son, Ben, was drafted by Collingwood in the 2009 National Draft.
