It is predicted that H$\alpha$ emission line at the early nebular epoch oftype II-P supernovae may display robust observational effects of damping wings.This is illustrated by Monte-Carlo simulations. The strength of damping wingeffects may be used to constrain parameters of the line-emitting zone. Ananomalous redshift, width and red wing of H$\alpha$ revealed by SN 1997D on day150 are explained in terms of damping wing effects.Comment: 8 pages, 2 figure
