"I can't remember anything. As soon as I came round I was absolutely fine," the 33-year-old said.
"It was a little clash of heads and these things happen in football.
"The main thing was to get the three points.
"I watched their penalty in the dressing room and then saw that we got our own.
"I was just praying that we scored because to get four points out of six from the last two games is fantastic.
"I went out onto the pitch at the end because I wanted to celebrate with the lads."
Carragher added: "Some of the players we had out there, because of the injuries we had, still qualify for the youth team so it was a really good team performance."
