"FoxSports.com reported Saturday that Tom Glavine is considering filing a grievance against the Braves over the reasons for his release. The report said the lefty's agent, Gregg Clifton, had spoken with a labor attorney and the players' union.

The collective-bargaining agreement states that players can't be released by their teams because of financial reasons. Glavine would have received a $1 million bonus if he was activated from the disabled list to the major-league roster.

Braves general manager Frank Wren and CEO Terry McGuirk have stated that Glavine was released strictly for performance reasons - because the team didn't believe he could be successful at the major-league level."
