The junior tore the lateral meniscus in the knee in a game against Syracuse on Wednesday.
"If they can go in and repair my knee, I'll probably end up missing the rest of the season," Dyson said Saturday while sitting on the bench before Connecticut played Seton Hall. "The recovery period from that is about four months."
Dyson said if the surgeons can't repair the knee, they would clean the knee out and he probably would be ready in four weeks. However, he said he would be hesitant to return because he hopes to have a professional career.
"It will do a lot of wear and tear on my body, if they do clean it out because I'll have no meniscus there," said Dyson, who was averaging more than 13 points, second on the team. "I want them to go in and see if they can go in and repair it."
Senior Craig Austrie and freshman Kemba Walker will replace Dyson, who believes the Huskies can succeed without him.
"I feel we're still championship quality," Dyson said. "We have enough players who can step up and fill that void of me being out. I know Craig is going to step up and play a lot of minutes and do a lot of the things I was doing out on the floor."
Dyson was injured when he banged knees with a Syracuse player as he fought through a screen. He had to be helped from the court.
Initially, he felt the injury was a bone bruise.
"Once I got up the next morning, I knew it was more than a bone bruise because I was in a lot more pain and my knee was starting to swell up," said Dyson, one of the Huskies' top outside threats.
Dyson felt devastated by the injury.
"It seems every time I get off to a good start something happens that pulls me back down," he said. "I just got to come back and start fresh next season."
Dyson started all 24 games for UConn. Coach Jim Calhoun called him a big part of UConn's 23-1 start.
