Prospects at positions of need continue to parade through UPMC Rooney Sports Complex, with highly regarded cornerback Christian Gonzalez headlining four prospects hosted by the Pittsburgh Steelers for official pre-draft visits Thursday.

TCU guard Steve Avila, South Carolina cornerback Darius Rush and Georgia Tech defensive lineman Keion White also were at the Steelers’ facility Thursday, exactly three weeks before the NFL Draft is scheduled to begin.

A 6-foot-1, 197-pound physical cornerback who ran the 40-yard dash in 4.38 seconds at the combine, Gonzalez is considered as a talent perhaps worthy of a top-10 pick. The Steelers, who are expected to target cornerback, have selections at No. 17 and No. 32 overall.
