DALLAS — The Colorado Avalanche will get a big boost in its quest to save its season Wednesday night. Devon Toews, who missed Game 4 with an illness, will return to the lineup for Game 5 at American Airlines Center. The Avs are down 3-1 in the series, and face the first of three potential elimination games. “He was pretty sick last game,” defense partner Cale Makar said before coach Jared Bednar confirmed Toews’ return.
