4:45 PM PT -- TMZ Sports has learned that Greg Robinson was busted with 156.9 pounds of marijuana, according to law enforcement docs.
Robinson -- who was also with ex-NFL player Quan Bray -- were stopped around 7:15 PM on Monday evening after a Border Patrol drug-sniffing dog alerted to the rear cargo door of their 2020 Chevy Tahoe.
The agents performed a follow-up search and located several vacuum-sealed black bags full of a green leafy substance.
Border Patrol tested the substance and it came back positive for marijuana.
BP says they also found 23 mason jars, a can sealing machine, an electronic scale, and $3,100 in cash in Bray's jeans.
