Can't seem to scrape tbody from this website

I'm trying to scrape data from this website: https://web.archive.org/web/20130725021041/http://www.usatoday.com/sports/nfl/injuries/

page = requests.get('https://web.archive.org/web/20130725021041/http://www.usatoday.com/sports/nfl/injuries/')
soup = BeautifulSoup(page.text, 'html.parser')
soup.find_all('tbody')

soup.find_all('tbody') returns []. I'm not entirely sure why.

This is the tbody part I'm trying to scrape out:

<tbody><tr class="page"><td>

Could someone help me out and let me know why the find_all on tbody returns an empty list? Even when i try tr with class page it returns an empty list.
