The Everton defender suffered a cut above his left eye in the first-half challenge with Newcastle's Senegalese striker and had to leave the pitch to receive treatment.
He returned with 10 stitches but played the whole 90 minutes as Everton recorded a comfortable victory at St James' Park, boosting their hopes of overhauling fourth-placed Arsenal in the bid for UEFA Champions League football.
"The head's fine, I can't really remember much of it," he told Everton's official website.
"I looked down and there was some blood dripping down so I went off, got sorted and came back on.
"I think there's about eight to 10 stitches. It was a cut but I wanted to get back on the pitch.
"They (the medical team) train a lot to do these type of things and so a big thanks to them. They did a really good job and I was back out on the pitch really quickly."
