This Tuesday marked the day that the Oakland Raiders started their organized off-season activities (OTAs).

Though, one major name player did not show up to workout with the Oakland Raiders. Head coach Jon Gruden shared this as to the unexplained absence of wide receiver, Antonio Brown.

Perhaps Gruden knows an explanation, but he is just failing to share that with those who are curious.

Nevertheless, Gruden does not seem to be overly concerned. Though, it is interesting that Brown would noticeably not show up to the start of OTAs with his new team.

Like Gruden says, maybe Brown will make an appearance with his team in the next few days. Until then, folks will continue to speculate.
