Allen Hurns

Allen Hurns signed a four-year, $40 million extension with the Jaguars on June 2. That's a lot of green. And the good news for Hurns is it's the type of green he can tolerate.

Hurns is allergic to grass. This can be a problem for an NFL wide receiver. Jacksonville's EverBank Field has a Tifway 419 Bermuda Grass playing surface, and Hurns, 24, has signed on to play on it through 2020.

But Hurns, a Miami native and former Miami Hurricane, has been around Florida grass his whole life, and he is a trooper.

From ESPN's Mike DiRocco:

"Hurns said he found out about his grass allergy by accident in high school. He was diagnosed with a seafood allergy and underwent skin testing from an allergist to see if he was allergic to anything else. Grass popped up, which explained why he would have rashes on his arms, legs and sometimes his neck after practices and games."

Hurns commonly wears long tights and a long-sleeve shirt on the field to fend off his allergy demons. He described his situation to DiRocco, as more of a "nuisance than a problem." On certain days, he needs to take a Benadryl before or after games, but on other days, his barely notices his condition.

"Sometimes I break out. Sometimes I don't," Hurns says. "... At times it gets pretty aggravating, but for the most part it’s been holding up good."

Hurns had a breakout sophomore season in 2015, reeling in 64 receptions for 1,031 yards and ten touchdowns in 15 games. The Jaguars believe he can turn into a superstar and that's nothing to sniffle at.
