LAS VEGAS — The Kansas City Chiefs defeated the Las Vegas Raiders 30-27 on Sunday, but the victory came at a significant cost as wide receiver Tyquan Thornton suffered a dislocated left ankle late in the fourth quarter.
Thornton was having the best game of his Chiefs career before the injury, catching five passes for 111 yards and two touchdowns. His night ended after a 55-yard reception from Patrick Mahomes with Kansas City trailing in the fourth quarter.

The Raiders refused to quit.

Las Vegas had another opportunity late in the game, but the Chiefs held on to secure their fourth straight victory.
Tyquan Thornton Injury: What Happened?
The biggest concern for Kansas City came late in the fourth quarter when Thornton suffered a serious left ankle injury.

With the Chiefs trailing 19-17, Thornton caught a 55-yard pass from Patrick Mahomes. Raiders safety Treydan Stukes made the tackle, and Thornton's left ankle twisted awkwardly as the two players went to the ground.
Thornton initially got up and appeared to celebrate the huge reception, but he was unable to put weight on the injured leg and collapsed back to the field.
He was eventually taken from the field on a cart. Chiefs coach Andy Reid said immediately after the game that the injury did not look good.
NFL Network later reported that Thornton had suffered a dislocated left ankle, which was put back into place by team medical staff. He is considered out indefinitely while he undergoes further evaluation.
Tyquan Thornton Was Having a Career Game
The injury was particularly painful for Thornton because he had just produced the best performance of his Chiefs career.
Thornton finished the game with:
5 receptions
111 receiving yards
2 touchdowns
22.2 yards per reception
Both of his touchdowns came from Patrick Mahomes.
His second touchdown came on an eight-yard reception in the fourth quarter, while his 55-yard catch later in the period appeared to put Kansas City in position to seize control of the game.
Instead, the play became the moment that left the Chiefs most concerned after the final whistle.
Patrick Mahomes Reacts to Tyquan Thornton Injury
Mahomes expressed sympathy for Thornton after the game, acknowledging how difficult it is for a player to suffer a major injury during a season.
The Chiefs quarterback said Thornton is one of the best teammates he has had and noted that he understood what it feels like to see a season potentially change because of one play.
Thornton had already established himself as one of Kansas City's most productive receivers through the opening weeks of the season, making his injury a significant blow to the Chiefs' offense.
Rashee Rice Injury Adds to Chiefs Concerns
Thornton was not the only Kansas City receiver to suffer an injury against Las Vegas.
Rashee Rice left the game in the first quarter with a right hamstring injury.
Rice caught a pass from Mahomes and appeared to pull up while attempting to gain additional yardage. He went to the sideline and later headed to the locker room before halftime.
Rice did not return to the game.
The initial reports indicated that Kansas City was taking the injury cautiously, but the Chiefs will need additional information before determining his availability for their next game.
Chiefs May Need More Help at Wide Receiver
The injuries to Thornton and Rice could force Kansas City to look for additional depth at wide receiver.
The Chiefs had already shown interest in former star Tyreek Hill, who remains available after being released by the Miami Dolphins earlier this year.
Following the Raiders game, reports indicated that Kansas City had remained in contact with Hill and his representatives.
A potential reunion would give Mahomes another familiar weapon alongside Travis Kelce, although any decision would depend on Hill's health, contract situation and the Chiefs' assessment of their current receiving group.
Kenneth Walker III Leads Chiefs to Victory
While Thornton dominated the receiving numbers, Kenneth Walker III was the offensive star who ultimately helped Kansas City escape with the victory.
Walker rushed for 177 yards on 22 carries, averaging 8.0 yards per attempt, and scored two touchdowns.
His biggest run was a spectacular 76-yard burst that helped keep the Chiefs' offense moving.
Walker then scored twice in the fourth quarter, with his two touchdowns coming just 19 seconds apart.
Patrick Mahomes Delivers Despite Pressure
Mahomes was not at his statistical best, but he made enough plays to keep Kansas City's perfect record intact.
The Chiefs quarterback completed 15 of 30 passes for 225 yards and two touchdowns, with both touchdown passes going to Thornton.
Mahomes also avoided an interception despite facing consistent pressure from the Raiders defense.
The Chiefs' ability to win despite Mahomes' modest passing numbers and multiple receiver injuries demonstrated the depth of their offense.
Kirk Cousins Keeps Raiders in the Game
Raiders quarterback Kirk Cousins gave Las Vegas a chance to pull off the upset.
Cousins completed 31 of 52 passes for 365 yards, two touchdowns and one interception.
He connected with Brock Bowers for a late touchdown that brought the Raiders within three points, but Las Vegas could not complete the comeback.
The Raiders dropped to 3-1 after suffering their first loss of the season.

What Does Tyquan Thornton's Injury Mean for the Chiefs?
Thornton's injury could have major implications for Kansas City.
He entered the Chiefs vs Raiders matchup as one of the team's most productive wide receivers, and his performance against Las Vegas showed how important he had become to Mahomes' passing attack.
The Chiefs also need to monitor Rice's hamstring injury.
With two key receivers potentially unavailable, Kansas City may need younger players to take on larger roles while the team evaluates its options.
The possibility of adding another veteran receiver, including a potential reunion with Tyreek Hill, could become one of the biggest storylines surrounding the Chiefs in the coming days.
What's Next for the Chiefs and Raiders?
The Chiefs remain undefeated at 4-0 following the dramatic victory over Las Vegas.
Kansas City will enter its Week 5 bye before returning to action against the Los Angeles Chargers on October 18.
The Raiders fall to 3-1 and will look to bounce back after narrowly missing out on a major divisional victory.
Chiefs vs Raiders Final Takeaway
The Chiefs vs Raiders game produced everything expected from an AFC West rivalry: late drama, explosive plays and a finish that went down to the final moments.
Kansas City escaped with a 30-27 victory, but the result was overshadowed by the injury to Tyquan Thornton.
Thornton's dislocated left ankle, combined with Rashee Rice's hamstring injury, leaves the Chiefs facing uncertainty at wide receiver.
For now, Kansas City remains unbeaten. But after a dramatic night in Las Vegas, the health of its receiving corps could become the biggest question facing the Chiefs heading into the next stage of the season.
