Twins' Royce Lewis: Dealing with minor knee issue

Lewis exited Saturday's minor-league game with a knee injury that is not believed to be serious, Jeff Johnson of The Cedar Rapids Gazette reports.

Lewis has apparently been dealing with the issue recently and aggravated it Saturday. Doctors have already evaluated the 19-year-old and determined there's nothing structurally wrong with his knee. Lewis recently returned to action after missing a couple of games with a leg injury.
