Umpire Steve Rippley said he will return to work today after missing a week to consider retirement.
Rippley, 45, called the NL office Wednesday with his decision. He will re-join his crew for a three-game series at Cinergy Field in Cincinnati.
"This is all I've done for 26 years,"
Rippley said. "It's been a while since I haven't worked in September."
Rippley is a crew chief and serves on the board of the umpires union. He worked his first big-league game in 1983.
He announced his intention to resign last week because he was angry with baseball over the dispute that has cost 22 umpires their jobs. Two of Rippley's former crew mates, Gary Darling and Larry Poncino, are among the umpires who will try to win their positions back through arbitration.
Rippley agreed to think about his decision at the request of the NL office. He was in North Carolina earlier this week attending the funeral of Kim Coble, wife of American League umpire Drew Coble, while his crew worked a series in Milwaukee.
Rippley said he received support from numerous umpires while contemplating his resignation.
"They respected whatever my decision was going to be," he said.
INJURIES: IF Luis Castillo's breakthrough season with the Marlins may be over.
Castillo dislocated his left shoulder during Wednesday's 5-4 victory over the Dodgers in 13 innings. He'll be sidelined indefinitely, but there's a chance Castillo can return before the end of the season, Manager John Boles said.
Florida also lost OF Todd Dunwoody, who fractured his left thumb when he was hit by a pitch in the 12th inning. He's out for the year.
