"It is not accurate," Dombrowski said. "I can 100 percent tell you that."
When contacted by MLB.com, Wilson's agent, Page Odle, also denied that any deal had been finalized.
The Star-Ledger report had cited a "person familiar with the deal" as the source for the information. The newspaper stated no details of who else may be included in the deal.
The Pirates and Tigers have been in trade discussions centering around Wilson for some time now. Detroit made a serious run at Wilson at the 2007 Trade Deadline and had revisited the idea of acquiring Wilson at the end of this season, when it decided to part ways with shortstop Edgar Renteria.
Those discussions are ongoing, however, according to one Major League Baseball official, as the two sides are still not close to an agreement, and are not expected to be making a deal on Thursday.
Wilson, a defensive specialist and the longest-tenured member on the Pirates club, hit .272 with 22 RBIs in an injury-plagued 2008 campaign. All eight of his years in the Majors have come with Pittsburgh, where Wilson has compiled 199 doubles, 358 RBIs and a .269 batting average.
He is owed $7.25 million in 2009, with a club option for 2010.
