Former Saint Dyer came off the bench to deny the south coast club all three points.
"I felt we put in a few good performances in the last couple of games and it is always going away to a team like Southampton that need the win and we were happy to come away with a draw," Dyer said.
"Southampton will always be in my heart. It was where I was from when I was eight years old.
"It is where I learned my trade, I've always had respect for Southampton and I hope they turn it around.
"I wanted to show my appreciation [in my celebration]. I was at the club for a long time and I just wanted to keep it to a minimum."
