EDEN PRAIRIE, Minn. — Five yards, seven seconds and one play remained.

Josh Robinson drew a one-on-one matchup with Mike Wallace, stayed step for step with the offseason acquisition and caused the pass from Teddy Bridgewater to be incomplete. Teammates took turns shouting for Robinson and meeting him mid-air during celebratory jumps.

The play near the sideline of the end zone ended a two-minute drill that started with the offense backed against its own goal line. It was just one snap during the team's sixth of 10 scheduled organized team activity practices, but it quickly summarized what OTAs and training camp are about: competing rep by rep, and that's fine with Robinson.

"It's been going good, just competing," Robinson said. "I've always been a competitor, and that's what I'm going to continue to do, to keep competing and trying to get a job."

Robinson, veteran Terence Newman and Jabari Price (in the slot) worked with the first team nickel defense Thursday while Xavier Rhodes and Captain Munnerlyn did not participate (Rhodes had a family commitment out of town). Munnerlyn said he thinks depth and competition will bring out the best in every cornerback.

"I've been competing since I've been in the NFL so it brings out the best in everybody," Munnerlyn said. "I know everybody in that room wants to play, so you've got to bring your best each and every day at practice and especially in the preseason."

Munnerlyn said making the type of play Robinson made can be "a confidence booster."

"Going against a guy like Mike, he's one of the top guys in the league, so it's definitely a confidence booster, but at the same time, it's still early," Munnerlyn said. "He's still got to keep his confidence and swagger going."

For Robinson, it was reinforcement of applying what he's drawing from Vikings coaches in his fourth year overall and second under Head Coach Mike Zimmer, Defensive Coordinator George Edwards, defensive backs coach Jerry Gray and assistant DBs coach Jonathan Gannon.

"Those are exciting plays when you do everything you've been coached to do and it ends up working up for you, you are proud and you want to continue to add to it," Robinson said. "It was a long, two-minute drive, so it was good to get off the field, especially knowing that they didn't any points out of it."

And, as for the challenge of covering Wallace, who scored nine of his 10 TDs inside the red zone last season in Miami, Robinson said, "He's good. He's a fast receiver, a guy you always have to respect on the deep ball."

CAPTAIN'S BOOT: Munnerlyn watched Thursday's practice from the sideline with a walking boot on his right foot. He told reporters the issue popped up on the first day of practices and he kept practicing through it.

"I didn't know what was wrong," Munnerlyn said. "On Monday, I couldn't run. I got an MRI and have a little something going on, so hopefully I'll be alright and ready to roll."

It might be a couple of weeks, he said, before he returns to action, but he's enjoyed seeing Adrian Peterson return to the field this week. Munnerlyn said the running back is "a guy who's in unbelievable shape, like he never lost a step and he's out to prove a point."

ELEVATION AND EVALUATION: Rick Spielman told "Voice of the Vikings" Paul Allen and Vikings analyst Ben Leber during the 9 to Noon KFAN radio show that Peterson's presence "raises and elevates" everybody's game.

Tuesday marked the 30-year-old Peterson's first practice with the Vikings since September, and Spielman liked what he's seen this week.

"Watching him for the first time he touched the ball on Tuesday, he looks like he's 24 years old, the way he's moving, the way he's running. He's kept himself in great shape. I know how important this game is to him, and he plays with a lot of passion. I'm excited to see him get rolling."
