The Detroit Tigers scratched catcher Alex Avila from Sunday's Game 4 lineup because of right forearm soreness.
He will be replaced by Gerald Laird.
Tigers manager Jim Leyland said Avila might be able to catch in an emergency, but probably could not be used as a pinch-hitter.
The team could make a roster move if the series continues beyond Sunday.
The Tigers are down three games to none in the best-of-seven World Series.
--The Colorado Rockies interviewed Jerry Manuel, Pete Mackanin and Matt Williams for their vacant managerial job, the Denver Post reported Sunday.
The Rockies also interviewed bench coach Tom Runnells, Rockies player Jason Giambi and former Rockies shortstop Walt Weiss since Jim Tracy resigned as manager Oct. 7.
---Several teams may show interest in outfielder Melky Cabrera if the Giants don't re-sign him.
Based on conversations with major-league executives, the New York Post reported that the Mets and Phillies may make a run at Cabrera.
The Giants also may try to re-sign him because Angel Pagan will become a free agent.
Cabrera hit .346 this season but was suspended for 50 games for testing positive for performance-enhancing substances.
