In the Huskies' final game, Watson tweaked his shoulder, spraining the AC joint. He went down to the Offense-Defense Bowl in Orlando, ready to play, but tweaked it again the first day of practice.
"I had a sprained AC joint from my last game, so I'm not playing in the bowl game," said Watson. "I came out here, hoping it would be better, but the first day of practice, I tweaked it. So I've got to take care of it for next year."
So Watson will be a spectator on Friday during the O-D Bowl.
Once Watson gets back, he'll turn his attention to his final official visits.
"It's pretty much a solid commitment to California," said Watson. "I'm still taking my trips and keeping my options open."
Watson will visit Cal on January 17th and then will visit UCLA on January 31st.
"I'm supposed to be playing in the West Coast Bowl on the 24th, but with my shoulder, I may not be able to play so if I don't, I may take another official that weekend," said Watson.
"I actually talked to the new staff on Tuesday night," said Watson. "If they finalize things and give me an offer, if they do that, I'll probably take my visit there on the 24th. We'll see how that goes."
UCLA will get his final visit just before Signing Day.
"UCLA is my last visit and I'm going to take that just to make sure I'm making the right decision," said Watson. "I love UCLA too. I've been to a lot of their games and they're an up and coming program. I watched the highlights of the bowl game. The main thing with them is trying to build a relationship with Coach (Kennedy) Polamalu. That will determine at the end of the day how serious I am about UCLA."
Cal, though, remains the constant.
"I've been up there for two unofficials and one of my defensive linemen is committed there, so I go with him. I know a couple of players and we hang out and have a good time. When I go on my official visit, there is honestly nothing really that they haven't shown me but they said for the visits, there would be a couple surprises for us. I'm pretty solid to Cal."
Watson said rumors of him decommitting for months had the Cal coaches concerned.
"They definitely were worried at some points, with all of the rumors that I was changing up and USC was my dream school, but I talked to them and told them what the deal is," said Watson. "USC was actually my dream school as a kid, but I never said that. An offer would be nice and I would consider them, but it wasn't quite like people said it was."
Watson said his relationship with the Cal coaches is the best.
"Coach (Pierre) Ingram is recruiting me but honestly they all are," said Watson. "Coach (Sonny) Dykes and Coach (Tony) Franklin are recruiting me hard too. That's why they stand out more than any other school. Other schools, its one coach from a recruiting area but Cal is all up with the coaches."
