Suh didn't participate in Tuesday's practice due to an unspecified issue, Jenna Laine of ESPN.com reports.

The veteran defensive tackle practiced the first two days of training camp after dealing with a minor wrist issue in June minicamp, but he was just an observer Tuesday. Laine notes Suh is always subject to the occasional maintenance day both in camps and during the season, and his activity Wednesday should provide further clarity on whether that was indeed the case in this instance.
