(Tualatin, OR) -- The Timbers will be short-handed when they host the Chicago Fire tonight. Captain Liam Ridgewell is likely out for six to eight weeks with a quad injury. Right back Alvas Powell and winger Darren Mattocks have left Portland to play with the Jamaica National Team. Portland is 7-and-7 and 5. Chicago leads the MLS with an 11-and-3 and 4 record.
