Mike Iupati

Mike Iupati left the team's practice on Aug. 19 with a knee sprain that required surgery and caused him to miss the first three weeks of the regular season, but head coach Bruce Arians announced that he will start at left guard in Week 4 vs. the Rams.

On Aug. 20, Arians confirmed that the lineman had surgery to repair his meniscus and expected him back in three-to-eight weeks, according to Darren Urban of Cardinals.com.

This is Iupati's first season with the Cardinals after spending five years with the 49ers. He was brought in to shore up an Arizona offensive line that protects Carson Palmer and to open up holes in the running game after the team averaged an NFL-low 3.3 yards per carry in 2014.

However, the 28-year-old has been hit by injuries the previous two years, missing a total of five games in that span.

Iupati, a 2012 All-Pro, can be dominant but needs to prove he can stay healthy to reach his potential. Now that he's back in the fold, look for the 3-0 Cardinals to build on their success with a stronger push from the offensive line.
