Thomas Calabro

Oh, doctor!

Glee has cast former Melrose Place star Thomas Calabro to play Puck's estranged dad, a show rep confirms.

Calabro, who played Dr. Michael Mancini on the original series for all seven seasons, will appear in Episode 18, according to TV Line, which first reported the news. Gina Hecht played Puck's (Mark Salling) mom back in Season 1.

Since moving out of Los Angeles' most infamous apartment building, Calabro also appeared on the CW's reboot of the series and guest-starred on an episode of Castle last season.

Glee returns with new episodes beginning April 10.
