Bristol County Sheriff Tom Hodgson told ABC News confirmed that two inmates at the jail in North Dartmouth were in an "altercation" Tuesday and that "one of them was Aaron Hernandez." Hodgson said neither man was seriously injured.

"We will be studying video and proceeding with interviews to determine why and how the incident took place to determine whether internal discipline or criminal charges are warranted," Hodgson said.

Hernandez is being held in segregation because he is a high profile inmate. It is unclear how he encountered the other inmate.

The former Patriots star is charged with the murder of Odin Lloyd, whose bullet-riddled body was found less than a mile from the $1.2 million mansion in North Attleborough where the one-time NFL star lived.

Prosecutors have also acknowledged that Hernandez is a suspect in a July 2012 drive-by shooting that left two men dead and a third wounded in Boston's South End during the Patriots' off season.

Earlier this month Bristol County prosecutors and Hernandez defense attorneys discussed another investigation involving what Assistant District Attorney William McCauley called a "national agency."

Prosecutors have been seeking official transcripts of phone calls Hernandez has made from the jail and visitor logs, a request that was denied by Superior Court Judge Susan Garsh.
