The Notre Dame Fighting Irish took out the natural grass field inside Notre Dame Stadium in 2014 and replaced it with field turf. After eight seasons of use, Notre Dame tore it out and replaced it with newer field turf.
The overall look is basically the same. Notre Dame has the interlocking ND monogram at midfield, the stripes in the endzone with its particular angles, the shamrocks on the 35, and the contrasting shades of green.
The one noticeable change is the font for the field numbers. Notre Dame is going back to a font similar to the one pre-artificial surface, but it does appear to be larger than the ones we remember from the 1990s.
