Chiefs' Tyquan Thornton Out Indefinitely After Ankle Injury vs. Raiders

Tyquan Thornton was carted off after a fourth-quarter ankle injury in Kansas City's 30-27 win over Las Vegas, and a former NFL team doctor sees a lengthy absence ahead.

Kansas City Chiefs wide receiver Tyquan Thornton left on a cart after injuring his ankle in the fourth quarter of a 30-27 victory over the Las Vegas Raiders. The injury, which occurred late in the game, dominated the aftermath of a win that kept attention on Kansas City's medical situation rather than the final score. Thornton has since been reported to be out indefinitely.

The play that ended his night was a 55-yard catch in the closing minutes of the fourth quarter. Thornton came down badly on the reception and briefly celebrated before realizing something was wrong. Medical personnel then attended to him on the field, and he was taken off on a cart.

Reports following the game said Thornton had suffered a dislocated ankle and that doctors put the joint back into place. He is now regarded as out indefinitely, and the plan calls for a full evaluation along with a second opinion before the Chiefs and the player know exactly how long he will be sidelined.

The injury cut short one of Thornton's best performances of the season. Before leaving the game, he had recorded six catches for 111 yards and two touchdowns, a major contribution on a night the team won by three points.

A medical opinion from outside the organization has added to the concern. David Chao, a former team doctor for the San Diego Chargers, reviewed the play and suggested Thornton could be facing an extended absence. He described the footage as "somewhat graphic" and pointed to the opposing directions of the ankle and the knee as evidence of the damage.

Chao went further in his evaluation of the injury itself. "That's a left ankle fracture/dislocation," he said. "It's very hard to dislocate your ankle, near impossible, without there being a fracture." His reading of the play is that the dislocation likely came with a broken bone.

Chao also warned against taking comfort from Thornton's reaction immediately after the catch. Because the receiver managed a short celebration before grasping the problem, some observers might assume the injury was minor. Chao said such moments can be misleading, and that the injury itself, not the initial response, is what should guide any judgment.

Chiefs head coach Andy Reid confirmed the worrying outlook when he spoke to reporters after the game. "Tyquan Thornton's ankle, that doesn't look good," Reid said. "He's going to fly back with us and we'll get further evaluation later here." The additional testing was set to take place once the team arrived back in Kansas City.

For now, Thornton has traveled home with the Chiefs and was described as being in good spirits. The organization has not provided a full diagnosis or a timeline for his return, leaving the next medical update to determine how costly the loss could be as the receiver waits to learn when he might play again.
