generate questions: Concerns were raised over whether Levi's Stadium's 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. As is customary for Super Bowl games played at natural grass stadiums, the NFL re-sodded the field with a new playing surface; a hybrid Bermuda 419 turf. NFL and Atlanta Braves field director Ed Mangan stated that the field was in "great shape" for gameday. However, the turf showed problem throughout the game, with a number of players needing to change their cleats during the game and player slipping during plays all throughout the game.
