Gritsyuk (upper body) participated in Thursday's training camp session, Amanda Stein of the Devils' official site reports.
Gritsyuk played in 66 regular-season games as a rookie last year, recording 13 goals and 18 assists, including five power-play points. If the 25-year-old winger can stay healthy this year, he should be capable of reaching both the 20-goal and 50-point thresholds, especially if he can secure more opportunities with the man advantage.
