For the second day in a row, the Pittsburgh Steelers visited with one of the top offensive linemen in this year’s NFL Draft class.

Penn State guard Olaivavega Ioane, a projected first-round pick, was one of three prospects to visit Tuesday. Ioane was joined by Iowa guard Beau Stephens and Ohio State tight end Will Kacmarek.

NFL teams are permitted to bring in 30 draft prospects for visits. The draft is April 23-25.

Ioane’s visit came a day after the Steelers met with Utah’s Spencer Fano, another first rounder, capable of playing tackle or guard.

The 6-foot-4, 320-pound Ioane is considered the most NFL-ready guard in this year’s draft class. He started 32 games at Penn State, and played the past 28 without allowing a sack, according to Pro Football Focus.

The Steelers have an opening at guard after starter Isaac Seumalo left in free agency, making Ioane a potential target at pick 21. Stephens is a potential Day 2 pick with Kacmarek likely going on Day 3.

Stephens (6-5, 315 pounds) started 13 games at left guard last season and earned first-team All-American honors from the Associated Press. He made 34 career starts.

Kacmarek (6-5, 261), who started his college career at Ohio, played 26 games with 16 starts over two seasons at Ohio State. A standout blocker, Kacmarek added 15 receptions for 168 yards and two touchdowns last season, earning honorable mention All-Big Ten honors.
