The clips, released Monday, feature Goodman and Barr reprising their roles as Roseanne and Dan Conner as they enjoy the holidays together by watching a basketball game.
Alicia Goranson as Becky Connor and Sara Gilbert as Darlene Conner are also seen in the teasers.
"You can't live in the past Dan," Barr jokes to Goodman, referencing how his character died in the series finale of Roseanne after nine seasons in 1997. "When things are gone, they're gone forever."
"I don't want to talk too specifically, but I wouldn't say we'll ignore the events of the finale," ABC Entertainment President Channing Dungey previously said to Entertainment Weekly about Goodman's character before confirming that he will not be dead in the revival.
"Dan is definitely still alive," he continued.
The second teaser involves Gilbert and Goodman explaining the rules of basketball to a clueless Barr.
