— Arkansas will hold its annual pro day today.

Four Razorbacks who participated at the NFL Scouting Combine last month – kicker Zach Hocker, defensive end Chris Smith, center Travis Swanson and defensive tackle Robert Thomas – are expected to participate.

Hocker did not participate in the 40-yard dash or any of the workouts at the NFL Combine, but he earned a 4.5 grade from the NFL. CBSSports.com rates Hocker as the No. 6 kicker in the draft class, but doesn’t project he will be drafted.

South Carolina’s Jadeveon Clowney received the most recognition at the NFL combine, but Smith’s 37-inch vertical was only a half-inch shorter than Clowney’s and tied for third among defensive linemen. Smith also ran the 40-yard dash in 4.71 seconds, which was eighth-best.

Smith received a 5.31 grade at the combine. CBSSports.com rates him as the No. 11 defensive end and projects him to be drafted in the third or fourth round.

Swanson earned the highest grade of any of the Razorbacks at the combine: 5.5. He wasn’t a top performer in any of the workouts, but he ran the 40-yard dash in 5.28 seconds and did 20 reps in the bench press.

He is the No. 3 center and projected to be picked in the third round, according to CBSSports.com.

After missing the final five games of the 2013 season with a broken leg, Thomas was able to only participate in the bench press at the NFL Combine. He did 32 reps, which tied for third most among defensive linemen.

The injury, which required surgery, could scare teams away. CBSSports.com rates him as the No. 39 defensive tackle in the draft and doesn’t project him to be selected.

Swanson, Smith and Hocker will be working out in front of NFL personnel for the third time. Swanson and Smith played in the Senior Bowl, while Hocker played in the East-West Shrine Game.

Fullback Kiero Small is also expected to workout Wednesday. Arkansas did not provide names of players participating in its pro day.
