Adrian Peterson Hospitaized Due to Allergic Reaction, Expected to Be Fine

It just keeps getting worse for Adrian Peterson.

The Vikings running back—who, it was recently announced, would start camp on the physically unable to perform list, according to the Associated Press—was hospitalized due to an allergic reaction on Monday.

1500ESPN.com's Tom Pelissero tweeted the news:

"

Adrian Peterson had an allergic reaction to seafood lunch, called ambulance, went to hospital, but he's ok and resting in dorm now. #Vikings

According to CBSSports.com's Joe Oberle, Peterson's symptoms included "shortness of breath" and "swelling in the face," but he's recovering nicely and is still expected to be present at rehab on Tuesday.

This incident comes just days after the Vikings officially announced that Peterson would start camp on the PUP list following reconstructive knee surgery. Last season, in the Vikings' penultimate regular-season game against Washington, he tore his ACL and MCL.

Via USA Today's Nate Davis, Peterson wasn't keen on the idea of starting camp on the PUP list and fought the move every step of the way. Vikings head coach Leslie Frazier told Davis:

"

He put up a fight. He said, "Coach, don't hold me back. Let me get out there." But we've got to be smart and we need to see him do a few things then make a determination. If he had his way, he'd be getting involved today.

"

Peterson, who has struggled with injuries throughout parts of his career since being drafted by the Vikings with the seventh overall pick in 2007, is understandably eager to get back onto the field. After the way his last season ended, he doesn't want to waste any time proving to his coaches and teammates—and to himself—that he's ready to go and that he can handle a full NFL workload.

When he's been healthy, Peterson has been a crucial component of Minnesota's offense, registering at least 1,000 rushing yards in all but one of his five seasons in the league and accumulating 67 total touchdowns.

But the last thing the four-time Pro Bowler wants is to get the reputation of a player who can't play a full season because he's been limited by injuries. Last season, an ankle sprain hindered him throughout the regular season, but he seemed to have recovered adequately—just in time to suffer a hit on a low tackle that would destroy his ACL and MCL.

And just when it seemed that the offseason had been going surprisingly well—just when it seemed like Peterson had been making a swift and impressive recovery from surgery, according to 1500ESPN.com's Judd Zulgad—there's this. A seafood allergy that lands him in the hospital. Another delay on his road to recovery.

Needless to say, he's going to be a lot more careful about what he eats for lunch in the future—at least, if he wants to get back onto he field sooner rather than later.
