Joey MacDonald could be back in the cage for the Calgary Flames Sunday when they face the Vancouver Canucks in their home opener. MacDonald backstopped the Flames to a 4-3 win on Friday, stopping 29 shots after Karri Ramo gave up four goals on 39 shots in a 5-4 shootout loss Thursday. The two could split action in the early going but do not forget about rookie Reto Berra as the Swiss netminder will start the season in the minors but is highly regarded.
