New Orleans released him this off-season for salary cap reasons in March (he was due a $3.25 million salary) and he received a $300,000 signing bonus as part of a three-year deal from the Seahawks about a month later.
Pathon, 29, has decent speed and can return kickoffs. But he was beat out by former Tampa Bay possession receiver Joe Jurevicius and Peter Warrick, who was given a $500,000 signing bonus on Aug. 30 by the Seahawks.
Pathon caught seven passes for 72 yards, including a 28-yard touchdown, in exhibition games with Seattle, but he reportedly wasn't thrilled about having to be on special teams coverage units and missed a meeting during training camp.
The Milwaukee Journal Sentinel reported that Pathon worked out in front of Packers officials on Tuesday, but left Green Bay without a contract in hand.
The Packers also may be considering free agents such as former Philadelphia veteran Freddie Mitchell, former New England receiver P.K. Sam and Seattle receiver Jerheme Urban, who was released Tuesday. Others who are available include Troy Edwards, Scottie Vines and Kelvin Kight.
