"For personal and family reasons I am re-opening my recruitment and potentially considering options closer to home," Watson announced on Twitter.
Bazley reopened his recruitment prior to Thad Matta's departure, while Goodwin and Ahrens decommitted shortly after.
The 6-foot-5 shooting guard is a native of St. Louis and attends Whitfield School (Missouri). Missouri and Saint Louis were among the schools to offer Watson before he committed to Chris Holtmann and Ohio State in early July.
Ranked No. 68 in the ESPN 100, Watson averaged 13.8 points and 3.9 rebounds with Ramey Jets United on the Adidas Gauntlet circuit this spring and summer.
