As the Predators begin the process of replacing injured forward Steve Sullivan for the next three months, General Manager David Poile said the first step is to look within the organization. But he's not ruling out the possibility of a trade. Poile pointed out that recently signed forward Martin Gelinas might step into a more prominent role due to Sullivan's back injury, and also noted that several Nashville forwards ? such as Vern Fiddler, Jordin Tootoo and Scott Nichol ? moved up to the first two lines at times last season.
