Update: Adrian Peterson speaks on sports hernia injury, surgery

Adrian Peterson's MVP season looks a bit more incredible now that the abdominal injury he played through in December proved serious enough to require surgery.

The Vikings released this statement this morning: Adrian Peterson had a surgical procedure done today by Dr. William Meyers, in Philadelphia, Pennsylvania. Dr. Meyers was able to successfully repair Adrian’s abdominal core muscle injury (sports hernia). We expect a speedy recovery with no long-term concerns.

Peterson rushed for 2,097 yards last season, eight short of the NFL record set by Eric Dickerson (2,105 in 1984). He was named the league's MVP on Saturday night in New Orleans, slightly more than a year after having major surgery on his left knee. Peterson was also named the league's offensive player of the year, and was first-team All-Pro.

And ... he played in the Pro Bowl in Hawaii on Jan. 27, although sparingly.

Now, it turns out, Peterson may have been pushing through severe pain for the Vikings' final six regular season games. In an interview Thursday afternoon with ESPN's Josina Anderson, Peterson said he suffered the sports hernia injury some time during the Vikings' 34-24 home win over the Lions on Nov. 11.

"I didn't know the extent I was hurt then," Peterson told ESPN. "I just remember getting twisted up pretty bad in an awkward position. ... "That next day I felt very uncomfortable in my groin and abdominal area. I thought to myself I'll just wait until I recover but I never did."

The Vikings played it safe with Peterson down the stretch of the season, repeatedly holding him out of practice in December and tailoring their approach so that he'd be as healthy as possible for game days.

"I knew I wasn't really practicing at all," Peterson said Thursday. "I wasn't able to lift because of the strain that it would put on those muscles on an upper- or lower-body workout. That was too much. It was mind over matter. It was just about doing what I had to do to push myself every week. My body was sore from the game and the sports hernia every Monday, so I did what I had to do to recover and get my body right.

"I just played through the pain. I ran on adrenaline."

Leading up to the Vikings' 36-22 victory in St. Louis on Dec. 16 -- a game in which Peterson ran for 212 yards -- he went on the injury report with what was being labeled an abdominal injury. Following his explosion against the Rams, Peterson was then listed as having an abdominal/groin issue which he said was "just normal wear and tear. I've been dealing with it the past couple of weeks. I've been doing the things I need to do as far as resting and conditioning and working out. It's all about that push to Sunday. I'll be ready to roll."

In Week 16, against Houston, Peterson carried 25 times for 86 yards. During that game, he said, the pain from the sports hernia reached its maximum.

"That was probably the worse I felt. That was the first time that I really doubted myself and questioned whether I would be able to continue the season. The pain was a 10 on a scale of 10."

Peterson rebounded in the season finale against Green Bay with 199 yards to challenge Dickerson's record and push the Vikings into the playoffs with a thrilling 37-34 win. The Vikings lost to the Packers on Jan. 5 in the wild-card playoff round 24-10 as Peterson had 99 yards rushing.

Recovery time on sports hernia surgery varies, since the seriousness of the injury varies wildly. But Peterson said his post-operative recovery time would be about 3-4 weeks.

Vikings teammate Geoff Schwartz (@GeoffSchwartz76) tweeted Thursday morning: "It's quite amazing. He's a beast. I made it 3 days in camp w/that injury before I needed surgery."

According to sportsmedicine.about.com: The typical sports hernia occurs when the muscle layer of abdominal wall in one specific area becomes thin relative to the other areas. This may result in a tear or strain in one of the abdominal muscles or the fascia of the abdominal wall. When that happens, the underlying internal organs, particularly the intestines, push up against the muscular wall and can cause significant pain. A sports hernia rarely causes any visible bulge in the muscle wall, so it is often overlooked for some time before it is diagnosed. The most common symptom of a sports hernia is a dull, aching pain in the lower abdomen or groin that gradually increases in severity. This pain generally increases with exercise or activities such as running or weight lifting.

At least three other Vikings have had surgery in the past couple of weeks. Defensive end Jared Allen had a torn labrum in his left shoulder repaired, punter Chris Kluwe had a meniscus tear in his left (non-kicking) knee fixed and center John Sullivan had a microfracture procedure on his left knee. All of those players played through their injuries this past season, none missing a game.
