Exclusive DetailsThe New England Patriots don't give a crap about Aaron Hernandez -- at least not enough to visit the guy in jail ... 'cause TMZ Sports has learned, not a single one of his former teammates has come to see him in the slammer.
It's been 8 months since the former star TE got locked up ... and sources at the Bristol County jail tell us, exactly ZERO of his "friends" on the team have stopped by to cheer him up.
Aaron gets a whopping 1-HOUR a week to see visitors ... and he can divide that time amongst up to 5 people -- one at a time -- however he pleases.
But here's the thing ... all visitors need to be approved by Aaron in advance. So if Tom Brady wanted to drop by, he'd have to get in touch with Hernandez first ... which isn't so easy 'cause he can only use the phone during visitation time.
But hey, at least Aaron's still got his porn ... oh, wait.
