Former San Francisco 49ers linebacker Dre Greenlaw sustained an injury to his quadriceps while working out on Sunday; that much is not being debated. The issue should not sideline him for any portion of training camp or the regular season, according to the most recent published reports.

Just a little more than one month after he signed a three-year, $31.5 million contract with the Denver Broncos during NFL free agency, linebacker Dre Greenlaw has suffered a "serious quad injury," according to a report from Jennifer Lee Chan of NBC Sports Bay Area.

One of the Broncos’ prized free agent additions is set to miss time during the club’s offseason program but avoided a potentially more serious injury.
