After concluding its four-game road trip with a 5-2 loss at Florida Saturday night and traveling back to Denver, the Avalanche practiced Sunday at Family Sports Center. Four veterans — defensemen Erik Johnson and Fedor Tyutin, plus wingers Rene Bourqe and Jarome Iginla, didn’t practice. Bourque and Tutin have been battling groin injuries, while Johnson and Iginla were on maintenance days.
