Arizona Cardinals left tackle D.J. Humphries has been diagnosed with a dislocated kneecap and will be sidelined for the next three months, according to NFL Network's Ian Rapoport.
The news comes after head coach Bruce Arians told reporters Humphries "probably" tore his ACL during Thursday's 22-16 loss to the Seattle Seahawks at University of Phoenix Stadium, according to AZCentral's Kent Somers.
"It's just a shame," Arians said, per Kyle Odegard of the team's official website. "The guy was playing fantastic."
