Four teams remain in the Kris Russell sweepstakes, according to TSN's Pierre LeBrun.

The free agent defenseman continues to weigh offers, with interested clubs keeping cap space open to sign the veteran defender. LeBrun believes Russell will sign prior to the season opening Oct. 12.

The Ottawa Senators, one of the teams pursuing Russell, confirmed Thursday to no longer be in the running. However, Russell's former club, the Calgary Flames, are believed to still be in the mix.

Russell, 29, split last season between the Flames and Dallas Stars, recording four goals and 15 assists through 62 games.
