Donovan, 25, signed a one-year deal with the Sabres on the opening day of free agency after spending his entire professional career with the Isles organization.
The fact he’s being waived isn’t a huge shock. Donovan failed to draw into a single Sabres game this year despite a whittled-down blueline; Jake McCabe, recently called up from AHL Rochester, drew into the lineup for Monday’s win over Columbus at the expense of Carlo Colaiacovo, who played the first two games of the year.
The fact both McCabe and Colaiacovo were ahead on the depth chart didn’t bode well for Donovan. Today’s move could also suggest that Zach Bogosian, who hasn’t played this year due to injury, is ready to return.
