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.

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.

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.
