Character concerns continue to plague Boston Celtics rookie Robert Williams.
The forward out of Texas A&M missed Boston's first summer league practice on Sunday after missing his flight back to the city following his introduction at TD Garden on Friday, according to ESPN's Chris Forsberg.
This comes after Williams missed his introductory conference call with reporters after he overslept last week.
The 6-foot-10 big man slipped to 27th overall in this summer's draft due to character concerns among league circles, and this latest incident won't do much to change that perception.
