9:43pm: D'Backs GM Josh Byrnes told Piecoro that team execs are heavily involved in trade talks and currently "talking about a lot of guys." He didn't mention Jackson specifically, but you have to think Byrnes would have squashed this rumor if the D'Backs and Tigers weren't talking about a possible Jackson deal.
8:27pm: Nick Piecoro of the Arizona Republic thinks the D'Backs are making a push for Jackson, but doubts they'd include Max Scherzer in a deal. As Piecoro points out, Scherzer's under team control for three more years than Jackson, who can become a free agent after 2011. Those three extra years add lots of value.

12:57pm: USA Today's Bob Nightengale tweets that the Tigers are close to trading Jackson, "perhaps as early as today." No word on the potential destination, but we'll keep you apprised in this post. What's more, Nightengale says the Tigers hope to trade Curtis Granderson this week.
The Tigers acquired Jackson from the Rays during the Winter Meetings last year, on December 10th.
