The Cajuns offense fell noticeably flat in Saturday’s 48-20 loss to Louisiana Tech without explosive playmakers like sophomore running back Elijah McGuire and Jamal Robinson in the game.

Robinson exited after a 12-yard catch in the second quarter. McGuire didn’t leave until early in the second half, but coach Mark Hudspeth said he hurt himself on one of the first couple of plays of the game.

The result wasn’t pretty.

“We took a step back Saturday,” quarterback Terrance Broadway said. “Jamal went down with a small injury … that kind of hindered our offense a little bit. But that’s no excuse.”

Tuesday, though, both Robinson and McGuire were on the field practicing.

McGuire was a full participant, though he looked like he was still feeling some lingering effects from his injury, which Hudspeth classified as a “tailbone” injury.

McGuire touched the ball on two of the Cajuns’ first three plays Saturday, one on a swing pass to the flat in which McGuire started in the slot, and the other a shovel pass in which McGuire started in motion.

Those were the last two times McGuire touched the ball on the opening series, and he went on to gain just 25 yards on nine touches after the opening series.

“We had some things we were wanting to get to with him that we never got to,” Hudspeth said. “He’ll be 100 percent come Saturday, and he’ll be ready to go full force.”

Robinson, whose left leg was heavily taped, was practicing only in a limited capacity, but Hudspeth sounded confident about his chances after watching him move around in practice.

“He made positive progress today,” Hudspeth said. “We felt a little better about the work he got in today. He left practice a little early to get some additional treatment because we’re just trying to make sure he’s ready to go. We thought today was really positive.”

“He’s sore, but he’ll be fine,” Hudspeth said.

Martin likely done

Hudspeth said reserve defensive lineman Marvin Martin had to have surgery on either his MCL or his patellar tendon, and the prognosis isn’t good moving forward.

“It’s probably going to end his career,” Hudspeth said.

Martin played in 13 games a year ago along the defensive line and finished second on the team in sacks with three.

He made the switch from offensive to defensive line for his sophomore season and looked like he had a promising future. But chronic knee pain kept nagging at him.

“He was going to try and push through it,” Hudspeth said. “It’s been bothering him since the spring … He thought he could get through the season, but it just got to the point where it got too painful.”

Status report

The Cajuns got some more good news on the injury front Tuesday, as senior linebacker Jake Molbert (muscle fatigue) and junior defensive lineman Marquis White (ankle) both participated in team drills.

Molbert, who has missed both games so far, was a full participant. White was wearing an orange limited participation uniform.

“We think he’ll be 100 percent by Saturday,” Hudspeth said of White.

Linebacker Trey Granier and safety Sean Thomas were also limited participants Tuesday.
