(Seattle, WA)  --  The Seattle Sounders will host the Colorado Rapids tonight in the first leg of the MLS Western Conference championship.  The Sounders have a 13-5-2 all-time record against the Rapids, but Colorado has won the last three matches between the two teams.  Seattle forward Jordan Morris's status for the game is uncertain, as he's been nursing a strained hamstring he suffered in the second leg against FC Dallas.  Kickoff at CenturyLink Field tonight is set for seven o'clock.
