Unbelievable moment for Senators star Bobby Ryan — who returned to the ice in Ottawa on Thursday after taking 100 days off to go to drug and alcohol rehab and get sober … and he pulled off a HAT TRICK!!! The 32-year-old had stepped away from the team on Nov. 20 to focus on battling alcoholism through the league’s substance abuse program. Tuesday marked 100 days of sobriety — and Thursday night was Ryan’s first game back at the Canadian Tire Centre … where he was welcomed by adoring fans.
