NFL teams are allowed to have 53 players on their roster.
An NFL team has 53 men on its roster not counting injured reserve.
Current Number of Players on NFL Roster32 teams x 53-man roster = 1,696 players When its not regular/post season, teams are allowed to have 80 men...Not all teams carry the maximum. 80 x 32 = 2,560 players during the off-season/pre-season.
You could but it would be very risky. I have seen games where both quarterbacks were injured and the team had to use a running back to finish the game (Washington/Philadelphia, 1990 ... the 'body bag' game). I can't say that I know every player on every NFL roster but I can't imagine there is a team that carries less than three quarterbacks on their 53 man roster.
Practice Squad players do not travel to away games with their respective teams. Practice squad players are not elligible to play in games until they are added to their team's 53 man roster, so it would be pointless to bring them on the road. Check the link below for the portion f the NFL CBA that covers the Practice Squad.
