I'm assuming he doesn't have glaucoma?
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 26-year-old ex-NFL player
Quan Bray -- was 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.
According to the docs, Robinson and Bray were NOT reentering the country from Mexico -- rather they were trying to get from Los Angeles to Louisiana and hit the checkpoint on the way.
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.
There was a third person in the SUV -- who was not charged. During the stop, Robinson and Bray allegedly tried to get that person to take the fall for the weed.
BP says while in custody, agents observed a text notification on Robinson's cell phone from a contact listed as "Grow House Indoor."
Robinson and Bray are facing up to 20 years in prison, if convicted.
Robinson and Bray were teammates at Auburn. Bray -- a wide receiver -- played a few seasons with the Indianapolis Colts, but never really caught on in the NFL. He was most recently playing with the CFL's Montreal Alouettes.
