At least two organizations, including Comcast Corp., have suspended advertising on sports-talk radio station WEEI following racially insensitive comments from one of its hosts.

The cable giant and the City of Boston Credit Union have pulled their campaigns, effectively immediately, after midday host Christian Fauria imitated a well-known sports agent by speaking in a stereotypical Asian accent.

On Friday, WEEI suspended Fauria for five days, characterizing his behavior as an “insensitive and ill-conceived attempt at humor.’’ The former Patriots tight end is a co-host of the midday “Ordway, Merloni & Fauria’’ show.
