There was a lengthy delay in the second half when Carragher was left unconscious after a clash of heads with youngster John Flanagan.
The former England defender was eventually carried off on a stretcher, his neck in a brace, and given oxygen.
However, after treatment at the Emirates Stadium, the veteran Reds centre-half had recovered enough to run onto the pitch at the final whistle to celebrate a dramatic draw when Dirk Kuyt slotted home a last-gasp penalty just moments after Robin van Persie's spot-kick deep into eight minutes of stoppage time looked to have won it for the Gunners.
"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."
