NEW YORK (AP) _ Tim Allen is in a contract holdout, according to the actor who plays his sidekick on the ABC sitcom ``Home Improvement.''

Richard Karn, who plays flannel-clad Al on the network's top-rated comedy, told TV Guide the show's grunting comic star wants a schedule change.

``He either wants the show moved to 8 p.m. or to have stronger shows around us,'' Karn says in the magazine's Jan. 3 issue.

The network's contract offer for the 1997-98 season would pay Allen $1.25 million per episode, according to TV Guide, which offered no comment from either ABC or Allen.

If Allen doesn't get what he wants and the show ends this year, Karn wouldn't be too disappointed.

``It'd really be nice to try something different,'' he said.
