The school said Wednesday that all questions related to Shannon having gone through the NBA draft process last summer had been resolved. No specifics were disclosed.
Shannon, a preseason All-Big 12 pick by the league coaches, will be available to play when the Red Raiders (3-0) have their next game Saturday against Incarnate Word at South Padre Island, Texas.
School officials said before the season opener last week that Shannon, who did not hire an agent as he explored his NBA options, was being withheld from competition "out of an abundance of caution" to ensure all NCAA rules were followed.
The versatile 6-foot-6 guard averaged 12.9 points and 4.0 rebounds last season. He was Tech's top returning scorer.
