Original Story: The Los Angeles Dodgers and Boston Red Sox are in discussions on a massive deal that would send Adrian Gonzalez, Josh Beckett, Carl Crawford and Nick Punto to LA for James Loney, Jerry Sands, Ivan De Jesus, Rubby De La Rosa and a top prospect, reports Gordon Edes of ESPN Boston.

While many high-profile waiver claims in August typically amount to nothing, the Dodgers' claims of both Gonzalez and Beckett on earlier today may very well culminate in a blockbuster trade of epic proportions.

Both Beckett, who has 10/5 rights, and Crawford, who has a limited no-trade clause, would have to approve the deal, but neither are expected to block the trade, according to Sean McAdam of CSN Northeast. Adrian Gonzalez also has a partial no-trade clause, but the Dodgers are not on the list.

The top prospect on the Dodgers' end of the deal will be pitching prospect Allen Webster, reports Jon Morosi of FOX Sports. If a deal can be finalized, the Red Sox' pre-arbitration obligations for next season will drop massively from $106.9 million to just $45.6 million, reports Jeff Passan of Yahoo! Sports.
