Jefferson (arm) isn't listed on the Rams' injury report Wednesday, Jourdan Rodrigue of The Athletic reports.
Head coach Sean McVay didn't unveil the first-team skill-position players this preseason, but Jefferson may have missed time anyway due to what was initially believed to be a false positive test for COVID-19 and a right arm issue that caused him to wear a brace. Now healthy in advance of the regular season, Jefferson is set to serve as L.A.'s No. 3 wide receiver behind Robert Woods and Cooper Kupp. However, Jefferson may have to contend for reps with free-agent addition DeSean Jackson and 2021 second-round pick Tutu Atwell.
