The Facts: Robinson's agent confirmed a report Thursday that the receiver has re-entered an alcohol rehab facility. But Alvin Keels made it clear that Robinson's decision was voluntary and he has not violated the NFL's substance abuse policy.

Diehards Line:"Is Koren Robinson in rehab or at a rehab facility? Yes," said Keels, responding to a report that first broke on Profootballtalk.com. "Was Koren Robinson drinking? No. Was Koren Robinson forced by the NFL or the Vikings to go? No. Most recovering alcoholics seek treatment through the years. He's just being more proactive than in the past." Robinson denied the report -- before Keels subsequently confirmed it a second time. ... Ss much as we'd like to believe Robinson is taking good care of himself during a quiet time of the year, we'll continue to watch closely and report if/when more details emerge.
