Oregon freshman center Bol Bol, a 7-footer who starred early in the Ducks' non-conference schedule, has a stress fracture in his left foot that not only has sidelined him for four games but also may end his season — and likely his career — at the university, 247Sports' DuckTerritory.com reported Thursday, citing multiple unidentified sources.

Bol announced his season is finished in a post on Twitter on Thursday while also appearing to say his career at Oregon is done.

"Playing for my dream school under my favorite Coach Altman has been the Best part of my life and sadly it has come to end sooner than I would Like but thank you for all those who rocking with me & all Oregon fans [?] [?] thank you #GoDucks," he wrote.

Bol — the 7-3 son of late NBA player Manute Bol — has been a projected top-5 pick in most mock 2019 NBA Drafts, but the nature of his reported injury could conceivably have an impact on his draft status.

Through nine games, he averaged team highs of 21.0 points, 9.6 rebounds and 2.7 blocks.

Bol, a five-star prospect, was part of the highest-rated recruiting class in school history at No. 3 in the country. He was the nation's No. 4 player in the 2018 class, according to 247Sports' Composite Rankings. 

The Ducks, considered the preseason Pac-12 favorites, are 9-4 heading into the start of conference play Saturday against Oregon State.

Per DuckTerritory.com: Oregon also is missing sophomore forward Kenny Wooten (broken jaw), while sophomore forward Abu Kigab decided on Wednesday to transfer from the program in search of more playing time. That leaves Oregon with only four healthy forwards.
