Christian McCaffrey and Jaycee Horn suffered significant injuries during the Carolina Panthers' 24-9 victory over the Houston Texans on September 23, 2021. McCaffrey strained his hamstring in the second quarter and missed five games before returning on November 7. Horn broke three bones in his right foot during the third quarter, underwent surgery and missed the remainder of his rookie season. Both eventually resumed their NFL careers. As of November 2026, McCaffrey plays for the San Francisco 49ers, while Horn remains with Carolina and is recovering from a separate quadriceps injury sustained in September.
What Happened to Christian McCaffrey Against the Texans?
McCaffrey injured his hamstring during the second quarter of Carolina's Thursday Night Football matchup against Houston at NRG Stadium.
The running back appeared to experience discomfort while attempting to change direction on a rushing play. He left the field and received attention from the Panthers' medical staff.
After spending time inside the medical tent, McCaffrey walked to the locker room and was subsequently ruled out for the remainder of the game.
Before his departure, he had recorded 31 rushing yards on seven carries and nine receiving yards on two catches.
Head coach Matt Rhule confirmed after the game that McCaffrey had suffered a strained hamstring.
How Long Was McCaffrey Out With His Hamstring Injury?
The Panthers initially hoped McCaffrey would recover within several weeks without requiring an extended stay on injured reserve.
However, his recovery proved slower than anticipated. After returning to limited practice, he experienced discomfort that prevented him from resuming game action.
Carolina placed McCaffrey on injured reserve on October 16, 2021.
He returned to practice in early November and was activated from injured reserve on November 6.
McCaffrey played against the New England Patriots on November 7, ending a five-game absence.
His first game back included 52 rushing yards and 54 receiving yards, demonstrating his continued importance to Carolina's offense.
Why Did Christian McCaffrey Miss the Rest of the 2021 Season?
Although McCaffrey recovered from the original hamstring injury, he suffered a separate ankle injury during Carolina's November 28 game against the Miami Dolphins.
An MRI revealed damage severe enough to require another placement on injured reserve.
Because it was his second injured reserve stint of the season, the move ended his 2021 campaign.
McCaffrey finished the season with 442 rushing yards, 343 receiving yards and two total touchdowns in seven appearances.
His season-ending absence therefore resulted from the subsequent ankle injury, not a confirmed recurrence of the September hamstring strain.
What Happened to Jaycee Horn Against Houston?
Jaycee Horn, Carolina's first-round selection in the 2021 NFL Draft, suffered a serious right foot injury during the third quarter of the same game.
The rookie cornerback was backpedaling while defending a pass when he suddenly collapsed without contact from another player.
Horn immediately reached toward his lower leg and required assistance from the medical staff.
He was taken off the field on a cart and ruled out for the remainder of the contest.
Rhule subsequently confirmed that Horn had broken three bones in his right foot.
How Long Did Jaycee Horn's Broken Foot Take to Heal?
Initial NFL Network reporting suggested that Horn could miss approximately two to three months because of fractures involving the metatarsal region of his foot.
On September 27, 2021, the Panthers placed Horn on injured reserve and announced that he would undergo surgery.
Although Carolina did not immediately rule out a late-season return, Horn ultimately missed the remaining 14 games of his rookie campaign.
He finished 2021 with five tackles and one interception in three appearances.
Horn continued recovering during the following offseason and resumed football activities in 2022.
On August 1, 2022, Carolina activated him from the physically unable to perform list after precautionary treatment for soreness in the surgically repaired foot.
He returned for the 2022 regular season, appearing in 13 games and recording three interceptions.

Latest Christian McCaffrey Injury Update: November 2026
McCaffrey experienced another hamstring problem during the 49ers' October 2026 loss to the Atlanta Falcons.
Head coach Kyle Shanahan described the injury as mild, and the team's subsequent bye week gave McCaffrey additional recovery time.
He missed practice on November 4, participated on a limited basis on November 5 and returned to full participation on November 6.
San Francisco subsequently cleared him to play against the Las Vegas Raiders on November 8.
McCaffrey rushed 18 times for 68 yards and a touchdown while adding two receptions for 19 yards and another touchdown in the 49ers' 38-17 victory.
His participation confirmed that he had recovered sufficiently to return to game action, although future availability remains subject to the team's medical evaluations.
Latest Jaycee Horn Injury Update: November 2026
Horn remained with the Panthers and developed into one of the team's leading defensive backs, earning Pro Bowl recognition in the 2024 and 2025 seasons.
However, on September 27, 2026, he suffered a significant quadriceps injury against the Cleveland Browns.
Carolina placed Horn on injured reserve on September 30, requiring him to miss at least four games.
The injury is unrelated to the right foot fracture he suffered against Houston in 2021.
