EDMONTON, Alberta (AP) _ Edmonton Oilers GM Glen Sather says there may be more trades to come for the struggling NHL team.

``There's still a lot of things going on,'' Sather said after sending rugged defenseman Bryan Marchment and young forwards Steve Kelly and Jason Bonsignore to the Tampa Bay Lightning for defenseman Roman Hamrlik and forward Paul Comrie.

Sather would rather the media didn't try to guess what the possible future moves are, but he is still engaged in trade talks centering on Jason Arnott.

He is loathe to trade the big center but the New York Rangers have apparently changed their offer _ it's now Alexei Kovalev and 6-foot-6, 230-pound defenseman Eric Cairns _ and Sather is still mulling it over.

The New Jersey Devils also have an interest in Arnott and it appears the Oilers might be able to get scoring winger Bill Guerin and possibly Valeri Zelepukin, but Sather isn't wild about trading Arnott at age 23 for Guerin at 27.

Sather was asked if the Marchment trade took Arnott off the hot seat.

``It doesn't take anybody off the hot seat,'' he said.
