FAYETTEVILLE - Senior tight end Cheyenne O’Grady practiced Wednesday in a green caution jersey on a limited basis but should play Saturday against Portland State.

Kickoff is set for 3 p.m. at Reynolds Razorback Stadium.

O’Grady recovers from recent arthroscopic knee surgery.

Freshman receiver Trey Knox, also a starter, practiced Wednesday for the first time since missing the last eight practices with an illness. Knox will be reevaluated Thursday before a decision is made on Saturday’s availability.

Senior starting left offensive tackle Colton Jackson of Conway (recent foot injury) has practiced Sunday through Wednesday and will start Saturday, Arkansas coach Chad Morris said.

Junior college transfer Myron Cunningham, Jackson’s left tackle backup, starts at right guard backed by true freshman Ricky Stromberg.

“As I've mentioned before with Myron moving inside and Colton (Jackson) being healthy, we've got some interesting dynamics there I'm excited about,” Morris said. “We're athletic which is a good thing. We've got some depth, which is another great thing. Ricky Stromberg is gonna have an opportunity to play Saturday. I'm excited to watch him as well.”

Treylon Burks, the true freshman from Warren, starts at receiver and returns punts, Morris said. Burks replaces senior returner Deon Stewart (major knee injury).

“That's a trust position, and this young man's got an opportunity to be really special,” Morris said. “I think he's earned that (starting spot), and we've got the utmost trust in Treylon. I think he's earned that during camp.”

SCOUTING PORTLAND ST.

Starting senior QB Ben Hicks said Portland State plays an unorthodox defense that’s “awkward” to play against.

“Well, they are,” Morris said. “It’s a flex defense, and back in the day, that was a really popular defense. They’ve done a great job of ‘this is who they are and this is what they believe in.’ They can do some things that get your rules kind of off guard a little bit. You’ve got to be on point with the way they align. For the most part, that’s kind of what their base is and that’s what they do. They like to play a lot of man coverage behind it. When they do that, you’re going to see pressure coming from different areas.”
