Saturday marks the biggest deadline of the NFL preseason.

By 4 p.m. eastern standard time, all teams are required to trim their rosters down to 53 players on their active/inactive list. Teams will then have until noon the following day to claim any player placed on waivers due to roster cutting.

For many players who have battled throughout the preseason for a position, Saturday can be the most stressful day of the year. And it doesn't matter if you were just drafted in April or have been in the league for years — if a team doesn't think they have a spot for you, you're out.

Check out the list of the biggest name on each team in jeopardy of being cut by Saturday's deadline in the list below. The NFL season gets underway on Sept. 6 with a Thursday Night Football matchup between the Philadelphia Eagles and Atlanta Falcons.
