Morphology

sideliner = sideline (transparent) = side + line + er

The meaning follows directly from 'sideline' plus '-er' as someone who is on the sidelines and not actively involved.

Etymology

Sideliner comes from sideline 'the edge of a sports field' and side 'beside', giving the picture of a person standing at the edge of the action. That's why a sideliner means someone who is present at an event but does not take part.
