in the novel the cross over when did jbs dad have a heart attack

At Noon, in the Gym, with Dad

People are watching; the crowd is growing; Josh and Dad are balling. Josh is making moves and dribbling; Dad gets the ball, winks, dips, and sweats. Dad is heading for the hoop when he stops short, screams, clutches his chest, and drops the ball. Alexis calls 911 and JB rushes to get water to splash Dad’s face. He’s out cold. Josh does CPR, but nothing changes. There are sirens. Da's pulse is gone. His eyes shut.
