Only a bowling ball would give a true rebound from the wall, a football would squish around the corner and probably bounce back towards you, although the angle would be adjusted slightly depending upon whether there was more ball over the left side of the corner or the right side.
I'd make it rebound backwards but add a little bit of random left or right to it (assuming you're making a football game). You could make it accurate by taking the position of the corner, transform it into the local space of the ball, then work out whether it's left or right of the ball's centre, then adjust the rebound angle accordingly.
