The knee injury Los Angeles Rams wide receiver Odell Beckham Jr.'s suffered in Sunday's Super Bowl when his foot got caught on the artificial turf field has increased calls for the NFL to mandate grass fields at all stadiums.
Of the 32 teams in the NFL, 16 teams still play on artificial turf, including the Rams and Chargers at their shared home, the $5.5 billion SoFi Stadium in Inglewood, California.
The non-contact injury to Beckham's left knee, which some fear could be a torn ACL, led to an outcry on social media.
