The illness that has resulted in Backstrom's placement on injured reserve is a stomach virus, the Associated Press reports. Backstrom previously battled a stomach illness less than two weeks earlier, but it didn't end up costing him any time. However, it appears the latest bug he's dealing with is a little more problematic, as he didn't travel with the Wild to Winnipeg for Monday's game. He'll be eligible to return to action Wednesday in Columbus, but it's not known if he's made enough progress with his recovery to be available for the Wild.
