Cox, whose contract expires at the conclusion of this season, hasn't told the Braves whether he intends to return for the 2010 season, which would be his 25th as Atlanta's manager.
"This year isn't any different than any of the others," Cox said before Wednesday's game against the Mets. "Nothing has changed. Just let us complete the season."
Since beginning his tenure as the Braves' manager midway through the 1990 season, Cox has often worked with one- and two-year deals that have been agreed upon long before the final weeks before his contract expires.
But at 68 years old, Cox and the Braves have to look at his immediate future differently than they did during his younger years, when he led the club to 14 consecutive division titles and had no reason to discuss whether he could or should return for the following season.
Braves general manager Frank Wren chose not to comment on Cox's future.
Multiple sources have said that the club would be willing to bring Cox back as the manager for at least one more season.
Another of the club's top executives has also confirmed that when Cox ends his managerial tenure he'll be guaranteed the opportunity to serve in an advisory role with the club.
Cox's 2,403 managerial wins rank fourth on Major League Baseball's all-time list. He began his managerial career with the Braves in 1978, and then began a four-year stint with the Blue Jays before the start of the 1982 season.
Wanting to return to Georgia, Cox became the Braves' general manager before the start of the 1986 season, and assumed that role until he decided to return to the bench full-time before the start of the 1991 season.
