Wide receiver Antonio Brown will be at the Oakland Raiders' facility in Napa, California, on Tuesday, a source told ESPN's Adam Schefter.
Brown has not been with the Raiders since being limited in a practice and leaving early on July 30.
He posted on social media Monday that he was looking forward to rejoining his teammates on the field after he lost a grievance against the NFL over wearing his old helmet.
On Friday, Brown had a two-hour conference call with an independent arbitrator to argue why he should be allowed to wear his older helmet -- a 10-year-old Schutt Air Advantage model -- which he is thought to have been using his entire career.
