What happened: Laremy Tunsil left one-on-one work with athletic trainers after getting dinged. Mike Garafolo said there was no sense of major panic ahead of the evaluation.

Why it matters: The left tackle signed a two-year, $60.2 million extension in March, making his health central to Washington's offensive continuity. He anchors the line as the Commanders install a new offense during preseason.

What to watch: Test results and Tunsil's participation at the next practice will clarify his availability.
