New Jersey Devils defenseman Henrik Tallinder's season may be in jeopardy because of his slow recovery from a blood clot.Tallinder has been sidelined since Jan. 19 when tests revealed he was suffering from a blood clot in his left leg. The club originally thought that the defenseman would miss six-to-eight weeks."It's going to be longer than that," Tallinder said Wednesday. "You think you can skate more, but you can't...I can still feel it. It's kind of like a stiffness."Tallinder will have another medical checkup around March 15 to determine if he can return this season.The 33-year-old has six assists in 39 games for the Devils this campaign.
