Cardinals TE Todd Heap has been inactive for 10 games in a row. Heap's knee appears to be healthy, but he isn't moving well. Perhaps the Cards should have seen that coming with a 32-year-old that has a long history of medical woes. "He's got to show us in practice that he's full speed enough to be able to go, and that hasn't been the case," coach Ken Whisenhunt said. Athletic second-year TE Rob Housler has impressed of late, catching 17 passes over the last four games.
