Add another Cardinals player to the growing injury report.

According to Mike Jurecki, offensive guard Mike Iupati suffered a left knee sprain and will undergo an MRI.

ESPN's Josh Weinfuss reported head coach Bruce Arians said Iupati will see a doctor regarding his knee, but "doesn't know what's wrong with it."

Iupati was one of the team's big free-agent signings of the offseason. After spending five seasons in San Francisco, Iupati was expected to bolster an offensive line to protect Carson Palmer and reinvigorate the ground game.
