Jason Arnott continues to skate with the St. Louis Blues, who are expected to make a decision on whether to sign the veteran center by Sunday. Arnott's deal with the Rangers earlier in the season fell apart when he was unable to pass a physical. Arnott had offseason knee surgery and said Tuesday that he wants to see how the knee responds to on-ice work. "If everything goes well and my body feels good, hopefully we can both say yes and move forward and contribute to win," Arnott said. Sounds like we should know more by the end of the week.
