A wide reciever
Through the 2017 season, tight end Jason Witten has a team record 1,152 catches -- good for fourth place on the National Football League's all-time receptions list. He also has a total of 12,448 reception yards.
If the ball was caught by a legal receiver, it's called a reception and the player starts running downfield as fast as his legs can carry him. If it was caught by any lineman but an end, it's a foul.
For the passer, it's called a completion. For the receiver, it's called a reception.
