Davidson underwent right knee surgery in late November and was expected to miss 6-8 weeks. The 27-year-old has one assist in seven games during his first season with Chicago. He signed a one-year contract worth the league minimum after making the team on a professional-tryout contract during training camp.
The Blackhawks now have up to 30 days or Davidson playing in 10 games before he’ll need to clear waivers again for an AHL assignment.
Defenseman Jason Garrison had his contract terminated after he cleared unconditional waivers. He was placed on unconditional waivers Wednesday after he failed to report to the AHL following passing through regular waivers.
The 34-year-old Garrison signed with the Oilers on a league-minimum contract after appearing in training camp on a player-tryout contact. In 17 games this season, he has one goal.
Elliotte Friedman of Sportsnet said Garrison is “considering some overseas options.”
