TEMPE — Just when it looked like Marvin Harrison Jr. was back to his pass-catching ways in Sunday’s loss to the Tampa Bay Buccaneers, a heel injury midway through erased that thinking.

Forced out of play in the third quarter, the wide receiver was again relegated to the sideline after having to be sidelined for the entirety of the two games prior due to recovery from an appendectomy.

Could that time on the shelf extend yet another week?

Given the type of injury, Wednesday’s missed practice and the fact corner Max Melton sat out last week’s loss with “kind of a similar injury,” it’s a valid question.

Cardinals coach Jonathan Gannon told @BurnsAndGambo WR Marvin Harrison Jr. will see a doctor soon following his apparent heel injury during Sunday’s game.

“Those are tricky,” head coach Jonathan Gannon told Arizona Sports’ Burns & Gambo on Monday. “He kept going back in the game and you watch him run and he’s running great. But when he walks or he jogs, it doesn’t look great. It’s a tough injury, because it’s on his foot. Anytime he puts pressure on his foot, it’s tough. I know he’ll do everything he can to play. I know that.

“He was down with the appendicitis. I was like, ‘Buddy, you can’t control that.’ He was pissed that he missed two games. But he’ll get himself ready to go. If he can go, he’ll go.”

Yes, it’s early in the week with two more practices to go. Harrison could easily find himself back on the practice field and into the lineup come Sunday. Thursday and Friday are going to tell a lot about his potential availability.

Harrison isn’t one to miss games, either, appearing in 65 of 68 since he got to Ohio State in 2021.

But if he can’t go, the WR1 door is again wide open for Michael Wilson to step through.

Totaling 25 catches for 303 yards, the only thing missing from Wilson’s two-game run as Arizona’s WR1 was a trip or two to the end zone.

Whether or not he gets another opportunity to be Jacoby Brissett’s first read (other than tight end Trey McBride) is up for debate with Harrison’s status up in the air. What isn’t is the tough task any of the aforementioned pass catchers and quarterback Jacoby Brissett are up against this week in the Los Angeles Rams.

While the Rams have given up plenty of yards to opposing wide receivers this season (146.5 per game), L.A. has kept the touchdowns to the 10th fewest (nine).

The defense giving up the second-fewest points (17.5) in the league has also allowed just the eighth-fewest yards to tight ends (45.3 yards per game) and is middle of the pack in touchdowns allowed (five).

As for Arizona’s run game that has sputtered to say the least this year but looked a lot better on Sunday? It’s up against the No. 1 defense in touchdowns allowed (four).

So yeah, it’s going to be tough sledding across the board for a team looking to play spoiler with the postseason officially out of reach with last week’s loss.
