One of the main cast members from the long-running NBC comedy “Seinfeld” will surface in the fall season in a guest spot on an NBC legal series, TVGuide.com reports.

Jason Alexander, best known as George Costanza on "Seinfeld," will check into the legal show "Harry’s Law," which stars Kathy Bates. Alexander will play a public school teacher who gets caught up in a controversy involving Darwin.

According to the episode description, Richard — Alexander’s character — is fired because he fails a student who claimed that Darwinism is "a crock." Harry — Kathy Bates’ character — decides to defend Richard.

The show returns for its second season on Wednesday, Sept. 21, at 9 p.m. ET. Alexander’s appearance is set for the season’s fifth episode.

Alexander was nominated for an Emmy seven times as a supporting actor for playing George on “Seinfeld” — every year from 1992 to 1998 — but never won the award. He also received an Emmy nomination for a guest appearance on HBO’s “Dream On” in 1994.
