Robert Brown|Justin Herbert is out for the season: Here's every quarterback with a season-ending injury

They say the best ability is Robert Brownavailability, but that seems harder than ever for NFL quarterbacks this season.

Seven starting quarterbacks − a whopping 22% of the league's starters − have been sidelined this year due to season-ending injuries. The quarterback injury bug started Week 1 of the 2023-24 season with New York Jets' QB Aaron Rodgers (Achilles) going down in the team's season-opening drive. The list has continued to grow at an alarming rate throughout the season, with Los Angeles Chargers QB Justin Herbert (finger) as the latest addition as of Tuesday.

In addition to Rodgers and Herbert, Anthony Richardson (shoulder), Kirk Cousins (Achilles), Daniel Jones (knee) Deshaun Watson (shoulder) and Joe Burrow (wrist) all sustained season-ending injuries.

OPINION:This cursed season should finally put the 'NFL is scripted' conspiracies to rest

Week 11: Joe Burrow, Cincinnati Bengals

Joe Burrow, who became the highest-paid player in NFL history in September after signing a five-year, $275 million contract extension, suffered a torn ligament in his right wrist in the Bengals' 34-20 loss to the Baltimore Ravens on "Thursday Night Football" on Nov. 16. The injury to his throwing hand happened in the second quarter when he landed on it following a hit and appeared in visible pain following a touchdown pass on the next play. He underwent season-ending surgery on Nov. 27.

"I landed on the wrist a little bit," explained Burrow, who was hampered by a calf injury to start the season. "The next play, the touchdown pass I felt a pop in the middle of the throw."

Burrow, 27, won five of his ten starts this season, completing 66.8% of his passes for 2,309 yards, 15 touchdowns and six interceptions. This is the second time an injury has cut Burrow’s season short. He sustained a season-ending knee injury as a rookie in Week 11 of the 2020 season.

Watson was injured in the first half of the game, but was able to finish out the contest. However, he had season-ending surgery on his shoulder on Nov. 21.

Week 9: Daniel Jones, New York Giants

Daniel Jones, who signed a four-year, $160 million contact extension with the Giants in March, suffered a torn ACL in the team's 30-6 loss to the Las Vegas Raiders on Nov. 5. The injury occurred during the second quarter when Jones dropped back for a pass, his right knee buckled under him and he went down awkwardly. He missed the previous three weeks due to a neck injury.

Jones, 26, lost five of his six starts this season, completing 67.5% of his passes for 909 yards, two touchdowns and six interceptions. This will mark the second time in three years that an injury has ended his campaign early. In 2021, he was sidelined for the final six games by a neck injury.

Week 8: Kirk Cousins, Minnesota Vikings

Kirk Cousins suffered a torn Achilles in the Vikings' 24-10 win over the Green Bay Packers on Oct. 29. The injury happened in the fourth quarter when Cousins suddenly went down for a four-yard loss and limped off the field. He underwent successful surgery on Nov. 1.

Cousins, 35, won four of his eight starts this season, completing 69.5% of his passes for 2,331 yards with 18 touchdowns and five interceptions. He's started 87 games for the Vikings since arriving in 2018 and missed only two games: one when the team rested its starters in 2019 and another in 2021 after testing positive for COVID-19.

Week 5: Anthony Richardson, Indianapolis Colts

Rookie QB Anthony Richardson's first season in the NFL ended after only four games. Richardson suffered a reported Grade 3 AC joint sprain in his shoulder during the Colt's 23-16 win over the Tennessee Titans on Oct. 8 and the team announced on Oct. 18 that he would undergo season-ending surgery.

Richardson, the No. 4 overall pick in 2023 NFL draft in April, won two of his four starts, completing 59.5% of his passes for three touchdowns and one interception. Richardson missed one game earlier in the season due to a concussion.

Week 1: Aaron Rodgers, New York Jets

Aaron Rodgers suffered a season-ending Achilles injury just four plays into his highly anticipated Jets' tenure during New York's 22-16 overtime win over the Buffalo Bills on Sept. 11 on "Monday Night Football." The injury happened on a sack from Bills' DE Leonard Floyd. Rodgers got up before falling back to the ground.

"Before even an MRI, I knew what happened. I knew I tore my Achilles. I had popped my calf a few times… and it was not that sensation, so I knew that this was not a good situation," Rodgers, 40, said afterwards.

AARON RODGERS: How's the Jets QB rehabbing his torn Achilles so fast? Here's what medical experts say

He underwent season-ending surgery on Sept. 13 with Dr. Neal ElAttrache and promised a "damn good rehab plan that will shock some people." He did just that, blowing away general rehab timeline of six to nine months. Rodgers was cleared to return to practice in a limited capacity as the quarterback on Nov. 29,. although he remains on the injured reserve. He's not expected to return this season.
