Walker was traded to the Avalanche by the Flyers on Wednesday, Pierre LeBrun of The Athletic reports. In addition, Colorado received a 2026 fifth-round pick while sending Ryan Johansen and a 2025 first-round selection to Philadelphia.

Walker will add to an already deep blue line led by Cale Makar. With the Flyers, Walker saw limited power-play minutes and likely won't join either man-advantage unit with Colorado, limiting his offensive upside. With the addition of Walker, the Avs felt comfortable with sending Bowen Byram (illness) to the Sabres in a trade.
