Football Zombie, while just as durable as most other weaker varieties, wears a helmet that makes him even stronger than a Buckethead Zombie. There is also a Giga version that is only found in the Plants vs. Zombies Web Version which absorbs even more damage. He also appears taller than a average basic zombie.
He is based on an American football player, a person who plays American football, a sport played by 2 teams of 11 players on a rectangular field with goalposts at each end.

Marshal Zombie is very humble, he does not refer himself as a general. Before each assault, he is always well-prepared, but he still doesn't understand how he is still being beaten up badly.
Overview
Football Zombie absorbs 1600 damage, and its appearance changes upon absorbing 480, 940, 1400 (at this point, the football helmet is destroyed), and 1535 damage before dying at 1670 damage.
The player obtains the Hypno-shroom after beating Level 2-5, so they can try to hypnotize the Football Zombie to make the level easier when instant kills are not enough, and the Football Zombie is just as effective for the player as against them.
The Suburban Almanac also advises the use of a Magnet-shroom, which removes his helmet, making him no different than a faster Zombie. Otherwise, this zombie is very dangerous, being fast and having very high health, so tons of firepower will have to be piled onto him in order to defeat him with brute force. He's not the biggest threat, but never underestimate what he could do.
The use of heavy damage plants, such as Melon-pult or movement restricting plants, such as Snow Pea, Kernel-pult, and Winter Melon, are other options. If these options are unavailable, use an instant kill such as Squash. Spikeweed and Spikerock can heavily damage the zombie as he approaches the player's plants, though the two are better when in front of a Wall-nut, Tall-nut or a Pumpkin to stall him while being damaged. Also, Gatling Pea is useful to weaken their helmets quickly once the player buys them. Using Gatling Pea is better when combined with Torchwood.
Football Zombie also has a larger than usual hitbox, which means he can trigger an armed Potato Mine in a Pumpkin. This can either be a blessing or a curse, as while it allows the Football Zombie to be easily eliminated, it can cause the Potato Mine to miss other zombies.
Deploy this zombie when very large amounts of damage needs to be absorbed (sometimes, it may be more efficient to use a Ladder Zombie instead if there is a Snow Pea to avoid its slowing effects. Magnet-Shrooms are to be avoided per usual.
Giga-Football Zombie is a black and white Football Zombie that is only seen in the online versions of Survival Mode and Vasebreaker. Giga-Football Zombie is identical to the original Football Zombie but with the health of a Gargantuar, and serves as their effective replacement as Gargantuars were absent in online versions.
Gallery
Plants vs. Zombies Wiki has a gallery for Football Zombie.
In Zombies On Your Lawn, the Football Zombie states that he used to play football, contrary to his almanac description which states that he does not know what a football is.
However, as the first part of the description implies that he used to play the sport, he might be only unable to recognize a football.
Most zombies lose their left arm when they take enough damage. The Football Zombie loses his right arm instead (unless he has eaten a Hypno-shroom, which mirrors the zombie's sprite).
Football Zombie, Dancing Zombie (when moonwalking), Zombie Yeti, and the hypnotized zombies (excluding Football Zombie) are the only zombies in Plants vs. Zombies that lose their right arm before death.
If a Football Zombie chews on a Garlic, he will go to another lane without stopping or making a disgusted face.
Football Zombie's helmet is available in the Xbox Live Marketplace for 160 Microsoft Points.
Football Zombie himself has the same health as a regular zombie (equivalent to 10 normal damage shots); the only reason why his toughness is so high is because of his helmet absorbs seventy. Because of this, Football Zombie's hit points are on par with an Imp, despite him being much bigger than the Imp, and he has less hit points than a Pole Vaulting Zombie or Ladder Zombie (seventeen hit points each).
If a Football Zombie is hit by butter while running, he may get paralyzed in mid-air with both of his legs above the ground. This may also happen if he is frozen by an Ice-shroom. This happens due to him being technically on the ground at all times.
Football Zombie is the only zombie that can be frozen in mid-air. Balloon Zombies and Pogo Zombies can be slowed, but cannot be frozen while they still have their balloon and pogo stick, respectively.
Spikeweed and Spikerock can still damage Football Zombie when he is in mid-air, if he happens to be above them.
Football Zombie has the second toughest headwear, the toughest being Giga-Football Zombie's headwear.
He is one of the fastest headwear zombies, with the other being Digger Zombie while he is underground.
In the Nintendo DS version of the game, when a Football Zombie loses its arm, instead of showing his arm falling off, the game shows the arm of an ordinary Zombie falling off.
The football helmet protects Football Zombie from projectiles and some plants like Spikeweed even though they mostly hit him in the other body parts except for lobber plants.
This applies to any other headwear zombies.
Football Zombie (with his helmet) makes the same sound when hit as Conehead Zombie and Digger Zombie.
Football Zombie is one of three zombies to have facepaint, the others being Gatling Pea Zombie and Giga-Football Zombie. All of these characters have their facepaint under their eyes.
In the Nintendo DS version of the game, Football Zombie eats and runs faster.
Due to the Football Zombie not appearing in the web version when hovering over the Giga-Football Zombie it will instead be mislabelled as a normal Football Zombie.
On the I, Zombie seed packet for this zombie, his head is bigger than it should be.
Imp, Newspaper Zombie (after the newspaper is destroyed), Football Zombie, and Giga-Football Zombie are the only zombies that can look straight at the player's house.
Many promotional images for the game show the Football Zombie as having a piece of dirt stuck in the mouth guard of his helmet.
In the game, Football Zombie's eyes are red and he has black makeup on his face while in the artwork which is on promotional images, his eyes are normal and he does not have the eye black makeup on his face.
There is a glitch that when the Football Zombie is hypnotized, the dirt kicks in front of the cleats rather than behind.
A rare glitch exists in the DS version when Football Zombie eats a Hypno-shroom, he can run infinitely in one place until he dies. This has a higher chance of happening on Survival Mode when lag occurs.
For some reason the Football Zombie's eyes appear slightly red tinted, though not as red as a Giga-gargantuar's eyes. This red tint never appears again in any of this zombies subsequent appearances with new art including artwork from this game.
