Hossa suffered a groin injury during Monday's practice and likely won't play in Wednesday's game against his former team the Senators, reports the Atlanta Journal-Constitution. He tried to work out on Tuesday but wasn't able to and coach Bob Hartley quoted Hossa as "very doubtful" and said that the team will keep him out until he's absolutely 100% as they won't want the injury to linger throughout the season. Groin injury can be extremely tricky so it's anyone's guess how long Hossa will be sidelined. For the time being, fantasy leaguers should take him out of their lineups immediately.
