Robert Kraft testified that Aaron Hernandez told him he was innocent when asked whether he was involved in the murder of Odin Lloyd.
Kraft spent a little more than a half-hour on the stand Tuesday at the Fall River Justice Center after being called by the prosecution in Hernandez's murder trial.
Hernandez is charged with the June 17, 2013, slaying of Lloyd, who was dating the sister of Hernandez's fiancée.
Kraft said he found Hernandez in a weight room working out and pulled him into an adjacent office for a private talk.
"I understood there was an incident that had transpired, and I wanted to know whether he was involved, and if he was -- any player that comes into our system, I consider part of our extended family, and I wanted to get him help," Kraft said.
"What did he say?" prosecutor William McCauley asked.
"He said he was not involved," Kraft replied. "That he was innocent and that he hoped that the time of the murder incident came out because he said he was in a club."
