Iowa State basketball coach T.J. Otzelberger says junior guard Tamin Lipsey has returned to summer drills. The Ames native has been limited since undergoing a shoulder procedure back in April.

Lipsey is coming off an All-Big 12 sophomore season in which he averaged nearly 12 and-a-half points and near five assists. St. Mary’s transfer forward Joshua Jefferson also remains limited in drills. The six-eight junior underwent knee surgery in February.

Otzelberger says Jefferson may not be at full strength until preseason practice begins.

Summer drills wind down early next month and Otzelberger says it is about building team chemistry.
