Head coach Pete Carroll said after the game that Carson was undergoing tests on the injury, as he did not return to the game on Sunday. Before the tests were even done, the team doctors were already telling Carroll that it appears to be season-ending, especially with it taking place this late in the year.
Carson is now the second running back to go down within the last month for Seattle, as they also lost backup Rashaad Penny to a season-ending ACL injury. The 2018 first-round draft pick went down with a torn ACL, one week after powering the Seahawks to a clutch home win over the Minnesota Vikings on Monday Night Football.
The 11-4 Seahawks will miss Carson as they head to the postseason, which they have already clinched a spot for, as the tailback was the fourth-leading rusher in the league entering Sunday. He recorded a career-high 1,190 yards and seven touchdowns, but will now finish two of his first three seasons on injured reserve. This injury also sparks the rumors of a possible reunion with the retired Marshawn Lynch, who is expected to visit the team this week.
