Looks like Michael J. Fox's return to series television will be short-lived.

A source confirmed to ABC News that "The Michael J. Fox Show" has been pulled from NBC's prime-time lineup and will be replaced by "Hollywood Game Night," hosted by Jane Lynch.

All 22 episodes of the show were already in the can, but only 15 have aired so far. It's not clear what will happen with the remaining seven shows.

Fox's return to a leading role in a television series was highly anticipated following the actor's two successful sitcoms, "Family Ties" in the 1980s and "Spin City" in the late '90s.

But his new show was struggling to draw viewers. "Fox" was averaging only 5.1 million viewers for the slot.

It's time-slot neighbor, "Sean Saves the World," another show featuring a returning star, Sean Hayes, was already pulled by NBC after averaging just 4.1 million viewers.

At last month's Television Critics Association press tour, NBC chairman Robert Greenblatt had warned that he was "unhappy" with the numbers and the shows faced an "uphill battle."
