Jets wide receiver David Nelson missed the first week of OTAs with what coach Rex Ryan said was an “illness.”

But Nelson didn’t just have the sniffles.

Nelson said this week he had “a bug” that he picked up when he was bit by a mosquito in Haiti doing charity work. Nelson had a 104-degree fever and strep throat. The Jets told him to stay away and get better.

“I was quarantined,” Nelson said.

He returned this week to practice and got to see the Jets’ new-look receiving corps. Nelson was signed during the season last year and played well during the final few months. Now, he is in the mix for the No. 2 receiver job.

Nelson believes the Jets have receivers with different skillsets who can complement one another.

“We’ve got a really dynamic group,” Nelson said. “We’ve got guys who can do a little bit of everything. We’ve got some short, really fast guys, some short jukey guys, some tall, athletic guys that can stretch the field. We’ve got some possession guys. You name it as far as receiver we have it in that room. Now, the next step is to get everybody to play at that maximum ability and keep everybody healthy.”

Health has been a big issue for the Jets receivers over the past two seasons. Nelson was signed after Santonio Holmes went down with a hamstring injury last year. Nelson said if the wideouts stay out of the trainer’s room, the group can help the Jets win.

“I think we have what we need for this team in that [receivers] room if we can keep everybody healthy,” Nelson said.

Nelson was not the only Jet making his OTA debut this week. Rookie Calvin Pryor took the field for the first time Wednesday after having three wisdom teeth removed last Friday. The Jets kept him out of practice until he had the teeth removed.

The Jets coaches did not ease him into things. He was playing with the first-team defense on Wednesday.

“They’re throwing everything at me. I’m running with the 1s right now,” Pryor said. “It’s important that I learn my playbook and know the system. I feel like I’ve been doing a smooth job.”

Pryor said the biggest difference from the defense in college at Louisville and the Jets’ system is terminology. He said schematically they are very similar.

“It’s a little more aggressive, but it falls into the same category,” Pryor said.

Jets coach Rex Ryan said he put Pryor with the first team to see how he would handle it and to force him and safety Antonio Allen to communicate more.
