Irving is starting Tuesday night against Philadelphia. Irving started 31 consecutive games before he was injured. Cavaliers All-Star point guard Kyrie Irving is back in the lineup after missing three games with a bruised left knee. Irving said he may have overreacted after going down, but that he was "scared to death" that he was hurt more seriously. The third-year pro was sidelined after injuring his knee on an awkward fall last week at Indiana.
