Witten recorded the catch from a Matt Cassel pass in the first quarter of the Monday night matchup.
Witten, who joins Tony Gonzalez as the second tight end in league history to reach the mark, told ESPN’s Lisa Salters before the game that he would “just be honored to join that list.”
Witten entered Monday’s game with 998 career catches, 649 of which came for 7,287 yards from injured quarterback Tony Romo.
The 33-year-old, who is in the midst of his 13th NFL season, entered Monday’s game as Dallas’s leader in receptions and receiving yards with 55 and 508, respectively, this season.
A ten-time Pro Bowler and two-time first team All-Pro selection, Witten was selected by the Cowboys out of the University of Tennessee in the third round of the 2003 draft.
