The 6-foot-6 undersized power forward will make his pick and announce it at a press conference on Wednesday afternoon, according to his New Heights coach Kimani Young.
"He going to decide tomorrow," Young told Scout.com. "There's been a lot of speculation. I"m going to give him his moment. He'll do something small."
Pinkston, a top 50 prospect, is expected to choose Tennessee, Villanova, St. John's, West Virginia or Connecticut. There is, however, a report surfacing that has the Brooklyn (N.Y.) Bishop Loughlin standout headed to Tennessee.
The New York Daily News cited sources Tuesday afternoon that Pinkston would sign with Tennessee on Wednesday.
Pinkston averaged 23 points and 10 rebounds a game during his junior season at Bishop Loughlin.
