EUGENE — Tyler Dorsey is entering the NBA draft once again and this time he’s not returning to Oregon.

The sophomore guard announced on Twitter Monday night that he would turn pro and hire an agent, ending any opportunity for him to return to the Ducks. He declared for the draft last year without hiring an agent and returned to school.

“After this great college experience, I believe this is the time to pursue my dream of an NBA career and I am now announcing my intention to declare for the 2017 NBA draft with an agent,” he wrote. “I have carefully deliberated this decision with my family and feel the timing is right now to pursue my path to a professional basketball career.”

Dorsey is the first Dana Altman recruit at Oregon to leave early for a pro career, although Dillon Brooks and Jordan Bell also are considering an early entry into the draft.

Dorsey had his best stretch of games for the Ducks during the postseason when he scored at least 20 points in all eight games as Oregon lost in the title game of the Pac-12 tournament and reached the Final Four of the NCAA Tournament before losing 77-76 to eventual national champion North Carolina.

Dorsey averaged 14.6 points and 3.5 rebounds per game while shooting .467 from the field and .423 on three-pointers. He averaged 13.4 points and 4.3 rebounds as a freshman and started 74 of his 75 games in two years with the Ducks.

The 6-foot-4 guard from Los Angeles was an honorable mention all-Pac-12 pick as a sophomore after earning all-freshman team honors.

Dorsey averaged 23.3 points per game in the postseason and made 29 three-pointers. He had 27 points in wins over Rhode Island and Kansas before finishing with 21 against the Tar Heels.

“When I arrived at Oregon almost two years ago, my goal was to not only be one of the best scorers and lead guards in college basketball, but also to lead the Ducks to winning heights not seen in recent memory,” he wrote. “After participating on a Duck team that reached the Final Four as well as leading the NCAA tourney in scoring, it was one of the best experiences of my life and I’m truly blessed to have those memories.”

Dorsey was a four-star recruit out of Maranatha High School in Pasadena, Calif., where he averaged 34 points per game as a senior. He originally committed to play at Arizona and also was recruited by Kansas before signing with the Ducks.

Dorsey is considered a possible second-round pick in the NBA who could play professionally overseas if he is not drafted.

He played for the Greek national team at the 2015 FIBA U19 World Championships when he averaged 15.9 points and 5.0 rebounds per game. His grandfather is Greek and his mother, Samia, lived in Greece as a child.

Oregon is expected to return guards Payton Pritchard and Casey Benson and has signed five-star recruit Troy Brown Jr. along with guard Victor Bailey Jr. Dorsey’s departure leaves the Ducks with one open scholarship for next year.
