The Seattle Seahawks brokered a trade earlier this offseason with the Minnesota Vikings to trade for wide receiver Percy Harvin.

Now, the Seahawks are hoping to pull off another big trade involving the Vikings.

The Seahawks are attempting to trade for Vikings Pro Bowl defensive end Jared Allen with roughly three hours remaining until the NFL trade deadline, according to ESPN.

UPDATE: Now, ESPN and FOX Sports are reporting that Allen won't be dealt to the Seahawks, if he's traded at all.

Allen has a hefty contract, but his deal could be adjusted to get the trade done.

Per the report, a second team is intereted as well.
