The FA drug unit paid a surprise visit to London Road this afternoon.
The unit walked into the Peterborough reception area just fifteen minutes before kick-off.
Obviously it isn't known whether which, if any, players were tested, but usually tests are carried out on several players from each side.
Meanwhile 229 unusually quiet Hereford supporters watched the game this afternoon in which Hereford United were said to have had 49% of possession.
The Bulls had just three shots on target against twelve for the Posh.
Captain Ben Smith received a seven for his performance, otherwise fives and sixes were given to the Hereford players.
However some Hereford supporters thought Tamika Mkandawire was the Bulls man of the match. Perhaps he and Wayne Brown deserved a higher mark.
There were no bookings.
Hereford drop to 16th position after today's results.
14 Grimsby 44 -16 57
