Mike Pouncey's bad Sunday didn't end with a 27-17 loss to the New England Patriots.
The Miami Dolphins center was served a grand jury subpoena by Massachusetts State Police shortly after the Patriots' victory, SI.com reported.
SI.com, citing a source, reported the subpoena was related to the investigation into former New England tight end Aaron Hernandez, a friend and teammate of Pouncey at the University of Florida.
The website said its source indicated police were concerned with Hernandez's potential involvement in interstate gun trafficking and focused on multiple transactions involving Pouncey and Hernandez.
"Organizationally, we do not have a comment," Dolphins spokesman Harvey Greene said. "And Mike Pouncey does not have a comment."
Hernandez was indicted and pleaded not guilty to six charges, including first-degree murder, in September. Five other charges were weapons related.
