If the MRI confirms the injury, Watson's remarkable rookie season will be over.
The injury occurred on a non-contact play as Houston was preparing for Sunday's game against Indianapolis, according to the NFL Network. Whether or not that's the case, though, remains to be seen in the coming days since this injury occurred.
Watson is said to have gone down on a normal drill in which he was running the read option and he could face an eight to nine-month rehab process.
The injury comes less than a week after Watson's best game of his young season.
The 12th overall pick in 2017, Watson threw for 1,699 yards and completed 61.8 percent of his passes with 19 touchdowns and eight interceptions through half the National Football League season. He threw for 402 yards with 4 touchdowns, but Houston lost the game in thefinal minutes. He passed for 1,699 yards and rushed for 269 more and two scores.
That performance helped make him become the first rookie quarterback to ever win AFC Offensive Player of the Month honour. He was the team's starter in their opener, but he was replaced at halftime by Watson, who ran away with the job. It's unclear if the Texans will add another quarterback to the team.
