Coloradoavalanche.com is reporting that John-Michael Liles suffered a broken foot in the Minnesota game, and is expected to miss 4 weeks. This is a severe blow to the Avs struggling powerplay - Brett Clark is currently the only healthy defenseman with a PP point (with a whopping 5).
No word on a replacement call-up, although I wonder if that Avs will just go back to using Klee on defense. Even without Liles, the Avs have 7 defensemen on the roster, so I'm not sure it's a guarantee that a defenseman will get recalled.
