INDIANAPOLIS (AP) — Overwhelming “human gridlock” in Indianapolis’ Super Bowl Village is causing police to rethink crowd control just ahead of the big game.

Eleven people were injured Friday night as an estimated 50,000 people flooded downtown streets for a free outdoor concert by the band LMFAO. Two other people were injured Friday separate from the concert-going group. Indianapolis Public Safety Director Frank Straub said none of the injuries were serious, most involving shortness of breath or scraped knees.

Officials are still tweaking their downtown plan as they prepare for more concerts and activities before kickoff, and they seemed to be pleased with the early results.

There was bumper-to-bumper traffic on some streets heading into downtown Saturday, but as of 10 p.m., police had not reported any injuries or arrests.

Police made a total of 22 arrests Friday night, mostly for public intoxication.
