Mark Warburton's Glasgow Rangers kick off their league season with the visit of Hamilton to Ibrox on August 6.
The 24-year-old lasted only a matter of minutes in Rangers' 2-1 friendly win over Charleston Battery after suffering a facial injury.
Wilson was accidentally elbowed in the face by a Battery player and did not see out the lengthy remainder of the match.
The former Liverpool man has now revealed just what happened, claiming that one of his top teeth went through his lip.
“It happened in the first two minutes. It was nothing, really. My mouth was closed and my top tooth’s gone through my lip," he said via The Glasgow Evening Times.
“He was trying to protect the ball and his elbow’s come up and my head’s gone down. I got four or five stitches."
Goals from Harry Forrester and debutant Josh Windass proved enough for Rangers, who are gearing up for their Scottish Premiership return after a four-year absence.
Their first league outing comes at home to Hamilton on August 6, but there are six League Cup games to negotiate in a gruelling nine-day period prior to that.
From July 16 to July 25, Rangers face Motherwelll, Annan, East Stirlingshire and Stranraer in games which will test the strength of the Gers' squad.
