Michael Sauer was not able to participate in Wednesday's practice at the MSG Training Center, and following the workout Rangers head coach John Tortorella confirmed that the second-year defenseman had suffered a concussion during Monday's game against the Toronto Maple Leafs and would not be able to play Thursday at The Garden against Tampa Bay. Sauer suffered the injury when checked heavily by Dion Phaneuf and falling hard into the boards and on to the ice late in the third period of the Rangers 4-2 loss. "He's been diagnosed with a concussion, and he is day-to-day," explained Tortorella. "So we'll go play. (Anton) Stralman will go in, and I'm not sure what the pairs will be. But we'll go play. That's how we go about it. Other guys have carried the weight, too. We feel confident we are going to go about our business, and hopefully guys will get healthy, but until they do we'll just play." Sauer is the second top-four defenseman on the Rangers to be sidelined with a concussion this season, joining All Star Marc Staal, who has yet to play a game so far in 2011-12.
