(NECN: Kathryn Sotnik) - Massachusetts State Police have served Miami Dolphins player Mike Pouncey with a grand jury subpoena, according to Sports Illustrated.
Sports Illustrated says the subpoena was served less than an hour after the Patriots defeated the Dolphins at Gillette Stadium in Foxboro Sunday afternoon.
Writer Pete Thamel says he watched it happen, and broke the story.
"He was clearly surprised, I mean I overheard him say 'what's this about?' I don't think he had any idea," he says.
Thamel went on to say, "Dolphins officials who were milling about after the loss were also pretty dumb founded."
As for what the subpoena is about, Thamel said it's linked to former New England Patriots player Aaron Hernandez.
Hernandez has pleaded not guilty to murdering his friend and associate, 27-year-old Odin Lloyd.

He's also being investigated by a grand jury in Suffolk County in Massachusetts for a 2012 double murder in Boston.
"A source told me the grand jury subpoena is related to the Aaron Hernandez case, not any of the murder cases he's involved with now, but more in regards to potential gun trafficking that has been linked to Hernandez since the murder happened," Thamel said.
Pouncey and Hernandez's friendship goes back to Hernandez's college years in Florida.
That's where the two, along with Pouncey's twin brother, Maurkice, played together at the University of Florida.
Maurkice Pouncey now plays in the NFL for the Pittsburgh Steelers.
Sports Illustrated reports Maurkice Pouncey has not been subpoenaed in the case.
They also say Patriots owner Robert Kraft was not informed Sunday that state police were going to issue the subpoena to Mike Pouncey.
"The easy macro-take on what this means for Mike Pouncey is that it's not good. How bad it is, we'll certainly determine, but what he testifies and what police find from analyzing the records of transaction that they'll end up taking."
It's important to point out that Mike Pouncey has not been charged with a crime and may not be charged with a crime.
NECN has not been able to independently confirm the Sports Illustrated report.
Monday, Massachusetts State Police also had "no comment" on the matter.
