Even Brett Farve knows there’s a right way and a wrong way to retire.  From the San Diego Union-Tribune’s Jim Trotter.

Three days after announcing his retirement from the National Football League, former Chargers linebacker Junior Seau could be on the verge of returning.

Two league sources confirmed that Seau will fly to New England tonight and, if things go well, could sign with the Patriots by the end of the week.

Injuries and free-agent losses have depleted the Patriots’ linebacking corps, particularly in the middle. New England targeted Seau late last weekend, soon after word began circulating that he would announce an end to his 16-year career.

Seau, 37, is expected to play middle linebacker with New England. Current starter Tedy Bruschi is sidelined with a wrist injury and fellow inside linebackers Monty Beisel and Freddie Roach have been battling injuries as well.

On cue, The Globe’s Mike Reiss has a days-old Seau testimonial quote from Bill Belicheck…that reveals absolutely nothing.

On Thursday, Dallas acquired 4th year veteran WR Charlie Adams from Denver in exchange for a 6th round pick in 2007.
