Tim Tebow says the case in which Aaron Hernandez is charged with murder is heartbreaking and sad.
And he says his thoughts and prayers are with all the families involved.
Tebow spoke Friday after the first practice of the New England Patriots training camp. The quarterback played with Hernandez in college at Florida and at last month's Patriots minicamp before they cut the tight end after his arrest on June 26.
Tebow was asked if he was shocked that a player he's known for several years was linked to the investigation but said he had been instructed not to comment.
Hernandez is being held without bail after pleading not guilty in the shooting death of Boston semi-professional football player Odin Lloyd on June 17.
