Nginx rewrite without redirect

I want url domain.com/foo-111 to load contents from directory /bar/111 but not change url.

I created a rewrite rule but instead of loading contents of proper directory, it 301 redirects to domain.com/bar/111

My server config

server {
  listen 80;
  server_name domain.com;

  location / {
      root /var/www/domain.com;
      index index.html index.htm;
      rewrite ^/foo-(.*)$ /bar/$1 break;
      try_files $uri $uri/ =404;
  }
}
