These were among the notable players moved before the NHL trade deadline Wednesday.
Columbus completed three deals, including one acquiring Gaborik from the New York Rangers for three players. Columbus (15-14-7) sits 11th in a tightly packed race for the Western Conference's eighth and final playoff spot.
Buffalo completed its fourth trade in three weeks by trading Pominville to Minnesota in exchange for goalie Matt Hackett and forward Johan Larsson.
Conacher, second in the NHL rookie scoring race, was traded by Tampa Bay to Ottawa for goalie Ben Bishop.
Hopefully [Jonathan] has a year that pushes us, that is the organization, to speak to him next summer and looking for [a long-term contract]. Because the thought process is trying to get a goaltender, and hopefully it's Jonathan, to be the stabilizer for this franchise.
