“It’s a concern because Brian is a guy we’re counting on to give us the depth we’d like to have. For us, a year ago, he turned out to be a key player for us (when Ray Edwards missed the last four games). We’re still waiting to hear the results of his test.”

Two other players — second-year cornerback Marcus McCauley (knee) and third-year tight end Garrett Mills (ankle) did not participate in Tuesday morning’s practice but both are expected back soon. Frazier said McCauley could play in Friday’s preseason game against Seattle and Bevel said Mills needs to pass a few tests before he can get back on the practice field.
