Free-agent forward Patrick Kane requires at least another month of rehab as he continues to recover from hip resurfacing surgery in June, TSN Hockey Insider Darren Dreger reports.

Dreger adds that the Buffalo Sabres are among the teams with interest, though Kane could boost many teams once he's back to full health.

Kane had the surgery on June 1 and was given a timeline of four-to-six months for recovery. Dreger adds Kane has been rehabbing in Toronto since July.
