The Arizona Cardinals signed guard Dorian Johnson to a four-year rookie contract on Friday.
Johnson was the team's fourth-round pick out of Pittsburgh in last month's NFL Draft.
Johnson was seen as a second-round pick who slid to the fourth because of a medical recheck that revealed a health condition related to his liver. It's producing enzymes at a rate five times higher than normal, but the 6-foot-5, 305-pound Johnson said he has had the condition his entire life and it is being controlled through medication.
Johnson started 40 consecutive games to finish his college career and became the first Panthers offensive lineman to earn first-team All-American honors since Ruben Brown in 1994.
