The number of games is not divisible by three, so there will be one week with only one game and 6 byes. For example you could use the following 10 week schedule:
(4 8) (---) (---)
(5 7) (1 3) (2 6)
(1 8) (3 6) (4 5)
(2 7) (3 8) (1 4)
(1 7) (2 5) (6 8)
(1 6) (2 4) (3 7)
(2 3) (4 6) (5 8)
(5 6) (7 8) (1 2)
(3 4) (1 5) (6 7)
(2 8) (4 7) (3 5)
