The Oilers are actively shopping centermen Shawn Horcoff and Sam Gagner, and right wing Ales Hemsky.
According to one source close to the organization, the Oilers are closing in on a deal involving Horcoff and "several others pieces will be swapped" as part of a trade.
Horcoff, 32, has two-years left on his six-year, $33 million contract. While his annual salary cap hit is $5.5 million, he's set to earn $4 million next season and $3 million in 2014-15.
Hemsky, 29, has only one-year left on his current contract. He has been shopped around for the last two seasons and it's believed there is a good chance he will not start the 2013-14 campaign in Edmonton.
Several teams, including the Detroit Red Wings, New York Islanders, New York Rangers and Ottawa Senators, are believed to be shown interest in Hemsky.
Contract negotiations between the Oilers and Gagner's agent have been moving forward, but TFP has learned a deal is not close and a trade could be on the horizon.
MacTavish has received a lot of interest in Gagner, but the Oilers are set on upgrading their blueline and would require a top-young blueliner as part of any deal for Gagner.
The Oilers had been linked to Phoenix Coyotes defenseman Keith Yandle, though it's uncertain if the two teams have spoken recently.
Gagner, 23, is scheduled to become a restricted free agent July 5.
