The Old Town-Orono hockey team will regain the services of senior defenseman Dylan Street for Saturday’s home game against Presque Isle. Street spent 2 1/2 weeks at Boston Children’s Hospital after coming down with an infection related to a rare illness he has called hydrocephalus, an inflammation of the brain that can cause swelling and bleeding. He has a shunt, a small tube that leads from the brain to his stomach and drains the excess fluid from his brain.
