Seattle coach Jim Mora said Monday that Houshmandzadeh was on his way to Louisiana to attend the service and would return Tuesday night.
Mora says Houshmandzadeh "was almost like a big brother" to Henry. Henry died last week after falling from the back of a pickup truck during what police described as a domestic dispute.
Houshmandzadeh played with Henry in Cincinnati from 2005-08. He said "everyone" liked Henry and called his friend's death "unbelievable."
