Sunday is special for football, as most NFL games are played on Sunday. Many people devote their entire Sundays to watching football. Saturdays are usually kept open for college football games. Some NFL games also take place on Thursdays and Mondays.
The last NFL game on Sundays is played at night and is referred to as Sunday Night Football. This is usually a marquee matchup that draws in tons of viewers.
NFL players typically prefer to play on Sundays. Playing on Thursdays is usually more difficult, as they only have a few days to recover between Sunday and their Thursday night game. Some players have pushed for a change to only Sunday games.
NFL Sunday Ticket is a special television package sold by DIRECTV. The package allows viewers to watch every out of market game on Sundays throughout the year.
