FOXSports.com reports that the Marlins have had discussions with the Tigers regarding the power-hitting second baseman.
According to multiple sources, MLB.com has learned that the Marlins are not confident they will sign Uggla, who recently turned down a four-year, $48 million offer.
Prepared to move in another direction, the Marlins have been initiating and fielding calls for the 30-year-old, who belted 33 home runs and drove in 105 runs in 2010.
Along with having contact with the Tigers, the Marlins have received calls from at least two unidentified National League teams.
The General Managers Meetings are set for next week, and the Marlins are expected to actively hold discussions regarding Uggla.
The Marlins are prepared to use the money they have been planning to spend on Uggla on other parts of their club.
In conversations the Marlins have had with teams about Uggla, they have been asking for relief pitching in return.
Florida also is in the market for a catcher.
What's hindering the Marlins' conversations with other clubs is the uncertainty of whether Uggla would sign a multiyear deal. Uggla, who won his first Silver Slugger Award on Thursday, has one more season remaining in arbitration.
He is eligible for free agency in 2012.
If Uggla is traded, the Marlins are prepared to switch Chris Coghlan to second base and give prospect Matt Dominguez a chance to win the third-base job in Spring Training.
If Dominguez, a first-round pick in 2007, doesn't appear big league-ready in Spring Training, the team likely will pursue a veteran infielder for either second or third base. Dominguez has spent the past two seasons at Double-A Jacksonville.
Before talks with Uggla broke down, the Marlins had been planning on switching Coghlan from left field to third base.
