Mangold was carted off the MetLife Stadium field in the second quarter after suffering the injury on a Jets running play. Patriots defensive tackle Vince Wilfork collided with Mangold's leg on the play after he was blocked into the play by Jets guard Oday Aboushi.
The ninth-year veteran remained down for several minutes, surrounded by players from both teams before he was carted off. Dalton Freeman came in to replace Mangold.
According to Mike Garafolo of Fox Sports, X-rays revealed no break in Mangold's ankle. He will undergo a MRI on Monday to determine the full extent of the injury.
Mangold received praise on Twitter before Sunday's game for wearing a NYPD hat into the stadium before the game, presumably in honor of the two New York City police officers who were killed in a shooting on Saturday. Mangold also wore the hat as he ran onto the field for warmups.
Since the Jets drafted him in the first round of the 2006 draft, Mangold has played in 141 of 143 games.
