Typically there is one tight end used in an offensive formation. There are variations to formations that call for two tight ends. In certain formations a third tight end can be used, but will not be an official tight end for that formation as they will be lined up behind the line of scrimmage. A typical NFL roster holds three or four tight ends.
Tight ends (and H Backs) in the NFL can wear numbers 40-49 and 80-89.
Depending on the offensive formation, there can be zero, one or two tight ends in the game on any given offensive play.
