Left wing Alexandre Picard, center Peter Sarno, right wing Lindsay and defenseman Pushor were sent down to the Crunch, the Blue Jackets' top minor-league team. That left 30 players on the roster.
Lindsay played 106 games with Florida, Montreal and Atlanta, scoring four goals and adding nine assists.
Taken in the expansion draft, Pushor played 136 games with the Blue Jackets from 2000-02. He saw action with Pittsburgh and Detroit, playing for the Red Wings in the 1997 Stanley Cup season.
Picard was Columbus' first pick in the 2004 entry draft. Sarno played six games with the Edmonton Oilers in 2003-04.
Minnesota Wild: The Wild assigned center Patrick O'Sullivan to their top minor league affiliate in Houston.
O'Sullivan, Minnesota's second-round draft pick in 2003, played in two preseason games before hurting his shoulder. The 5-foot-11, 190-pound O'Sullivan skated for Mississauga of the Ontario Hockey League during the 2004-05 season and scored 90 points in 57 games.
The Wild, who open the regular season at home on Wednesday against Calgary, are hurting a bit up front.
Center Mikko Koivu hurt his left knee in Friday's exhibition game against Buffalo and will likely be out for a month. Right wing Marian Gaborik has barely practiced since training camp began because of a pulled groin. Center Todd White has not been cleared to return since sustaining a concussion nearly two weeks ago.
Koivu and Gaborik will probably begin the season on injured reserve.
