Sabres center Mikhail Grigorenko is back in Buffalo after the rookie first-round draft pick completed his junior season in Quebec.
Grigorenko practiced with the Sabres on Tuesday after being formally added to their roster. The Russian-born player opened the season in Buffalo before heading to the Quebec Major Junior Hockey League on March 15.
Interim coach Ron Rolston wants to see Grigorenko in practice because the Sabres haven't ruled out demoting the 18-year-old to AHL Rochester.
Grigorenko had a goal and four assists in 22 games in Buffalo. He had a goal and three assists in Quebec's regular-season finale, and led the team with 14 points (five goals) in 11 playoff games.
Buffalo plays at Boston on Wednesday, two days after the Bruins game against Ottawa was postponed after the bombings at the Boston Marathon.
