The passer is also known as a quarterback (QB)
If you mean quarterback Jared Zambransky, he now plays for the Edmonton Eskimos in the Canadian Football League, where he is currently the backup quarterback.
I don't believe you mean to say quarterback...Carson Palmer is almost never in the news making statements. I believe you mean wide receiver Chad Johnson.

He means that #52 is the middle linebacker.
it can mean tackles in stats, and can mean like tackle in positions.

No, it is not considered a tackle. Technically when a quarterback goes down behind the line of scrimmage it is considered a sack. However, when a quarterback takes a knee, he is credited with a -1 yard rushing but no defender is credited with the tackle/sack.
