There could be a baseball Hall of Famer between the pipes when the Colorado Avalanche plays on Sunday ... 'cause none other than Larry Walker will be the official emergency goalie!!!
Of course, the chances are slim the 53-year-old ex-MLB slugger will see any PT ... but it's not impossible. Walker would just have to beat out the other 2 goalies on the roster.
Remember, just 2 weeks ago, 42-year-old David Ayres -- the Carolina Hurricanes Zamboni driver -- had his name called after the team's 2 goalies got injured ... and the dude helped secure the win!
