Hamilton Academical 1 St Johnstone 0
St Johnstone are to investigate Richard Foster and Danny Swanson's controversial dismissals in Saturday's 1-0 defeat at Hamilton, with boss Tommy Wright promising no sympathy if they are found culpable.
The pair were sent off at half-time after fighting with each other, with punches and kicks seemingly thrown.
Chaos descended on the pitch and around the tunnel area as referee Don Robertson's whistle sounded to end a nondescript first half, and the two Saints players had to be separated.
Both were red-carded inside at the interval, leaving Saints to play the second half with nine men.
Wright said afterwards: "Until I have seen it, I can't really comment, but I have told the players in front of the rest that the club will investigate it.
"They have been told that if what is alleged to have happened, happened, I will and the club will come down on them as hard as we legally can."
"The players know that I won't show them any sympathy if what is alleged to have happened, happened."
