The Pittsburgh Penguins' newest offensive contributor is going to miss some time.
Sullivan added that the 23-year-old forward will be out "longer term" with what the coach would only classify as an "upper-body" ailment.
Aston-Reese scored four goals in a four-game span earlier this month after being promoted to Sidney Crosby's wing on the Penguins' top line. He has six points in 10 games since being called up from Pittsburgh's AHL affiliate in Wilkes-Barre/Scranton.
The Penguins signed the Hobey Baker Award finalist to an entry-level deal out of Northeastern University last year.
