Houston Texans rookie quarterback Deshaun Watson tore the ACL in his right knee during Thursday's practice and will miss the rest of the season. The Houston Chronicle confirmed the original report by NFL Media.
The injury occurred on what was described to the Chronicle as "a routine play," running a toss-sweep in a non-contact drill.
Watson was added to the injury report as limited and because he didn't appear to be in much discomfort, it wasn't considered serious. However, an MRI revealed the tear, and Watson will undergo surgery at some point.
A club source told the Chronicle, "It's a damn shame. No one thought he was hurt that bad right away. He's a tough guy, so he'll be back."
During his college career at Clemson, Watson suffered a torn ACL in his left knee, but continued playing wearing a brace.
After speaking to Watson, Clemson head coach Dabo Sweeney said in a statement, "I talked to Deshaun late this afternoon and we are disappointed, but he is a person who has had some setbacks in his life and always comes back stronger. Since he went through the rehab before, he knows what it takes. At least this happened in the middle of the season and he has had the opportunity to show what he can do.
"It would have been so much worse if it happened in training camp. I have no doubt he will come back from this. He has the resolve. His work ethic and drive are incredible."
This past Sunday, in a 41-38 loss to Seattle, Watson lit up the Seahawks with 402 passing yards while throwing four touchdown passes. Seahawks cornerback Richard Sherman told Seattle reporters Thursday, "It's just unfortunate; it's terrible news. Feel terrible for him and his family. He had such a bright future. He still has a bright future, but his rookie year is cut short.
"It just sucks that he doesn't get a chance to continue his season and finish it out. It's just a freak accident, man."
Watson had just been named NFL Offensive Player of the Month and AFC Offensive Rookie of the Month for October when he had 1,171 yards passing with 16 touchdowns and five interceptions. He also rushed for 145 yards on 21 attempts with a touchdown. He became the first rookie quarterback in league history to be named player of the month. He is currently tied with Philadelphia quarterback Carson Wentz for the league lead with 19 touchdown passes and his 103.0 passer rating ranks fifth in the NFL.
Texans defensive end J.J. Watt, who is on injured reserve with a broken leg, tweeted, "Minor setback for a major comeback. We've all seen what's possible, can't wait to see what's next. With you every step of the way 4."
The Texans will host the Colts Sunday with Tom Savage at quarterback. Savage started the season opener against Jacksonville and was replaced by Watson during the game after being sacked six times.
Without any other quarterbacks on the roster, the Chronicle reported the team will sign Matt McGloin, who played at Penn State when Texans head coach Bill O'Brien was the head coach there. McGloin entered the NFL as an undrafted free agent with Oakland in 2013 and was with the Raiders for four seasons. He was in training camp this year with the Eagles, but was released in the cutdown to 53 players.
