Harrison status unclear for Week 5

Marvin Harrison missed the final 2 1/2 quarters against Denver Sunday, and it's not clear if he'll be able to play in Week 5, the AP reports. "I don't think it's a long-term thing, and Marvin didn't think so either when I talked to him," team president Bill Polian said on his weekly radio show Monday. "But we haven't gotten the results of the MRI yet, so I can't tell you for sure."The Colts are reasonably straightforward with their injury disclosures, so we'll see what Tony Dungy has to say at the end of the week.
