His agent, Tommy Sims, said on Thursday a visit with the Packers has been set up but an exact date has not yet been finalized. That could depend on what happens during Walker's visit with the Chiefs on Thursday.
Walker, 6-foot-2 and 305 pounds, played for the Oakland Raiders last season under a one-year, $2 million contract.
He appeared in 15 games and posted 40 tackles with three sacks. Originally a seventh-round draft pick in 2009, Walker played his first four seasons for the Atlanta Falcons. He played 10 games as a rookie and then appeared in all 16 games each of his next three seasons.
Other than re-signing three of their own free agents – cornerback Sam Shields, outside linebacker/defensive end Mike Neal and tight end Andrew Quarless – the Packers have not signed anyone in free agency.
