Lucic had surgery on his left wrist while Kelly had a procedure to repair a herniated disc in his back. Chiarelli said both players are expected to be ready for the start of training camp.
Lucic had four goals and three assists in 12 Stanley Cup Playoff games but was held to one goal and two assists in the Bruins' seven-game loss to the Montreal Canadiens in the Eastern Conference Second Round. He didn't have a point in the final four games of the series.
Kelly last played April 8 against the Minnesota Wild. He had nine goals and nine assists in 57 regular-season games.
After being through it and seeing the other [outdoor] games on TV, just the atmosphere is spectacular. To stand here -- and we are essentially almost on the blue line -- and look up [into the stands] and knowing it is going to be packed and playing our biggest rival in this setting is going to be pretty special.
