    Sentence 1: What is the name of the turf  used in Levi's Stadium for the Super Bowl?    Sentence Z Concems were raised over  whether Levi's Stadiums field was of a high  enough quality to host a Super Bowl; during  the inaugural season, the field had to be re-  sodded multiple times due to various issues,  and during a week 6 game earlier in the  2015 season, a portion of the turf collapsed  under Baltimore Ravens kicker Justin  Tucker, causing him to slip and miss a field  goal, although the field has not had any  major issues since.
