Jalen Hurts is expected to miss the rest of the NFL season after doctors diagnosed blood clots in both lungs, ESPN and NFL Network reported.

The Philadelphia Eagles quarterback has deep vein thrombosis (DVT) and bilateral pulmonary emboli, according to an Oct. 19 statement from the team. He is clinically stable and has no significant functional limitations, they said, but needs blood thinners—and can’t participate in contact activities, including football, while taking them.

“Jalen’s prognosis is very good, and we expect a full recovery,” the statement said.

The news raises questions beyond football: How do you recognize a blood clot? What does treatment involve? And why can some people stop blood thinners after a few months while others take them for life? We asked doctors who aren’t involved in Hurts’ care what everyone should know.

Deep vein thrombosis, or DVT, occurs when a clot forms in a vein deep inside the body, often in the leg. Those veins carry blood back toward the heart. They’re different from superficial blood clots——Hurts’ original diagnosis—which form closer to the skin, explains Dr. Geoffrey Barnes, a cardiologist and vascular medicine specialist at University of Michigan Health.

The distinction matters because deep-vein clots are more likely to break loose and travel through the heart into the lungs. Once a clot lodges in an artery there, it causes a pulmonary embolism.

DVT often causes pain, swelling, and redness or a darker skin color. Patients commonly tell Barnes, “My entire calf and ankle are swollen.” One leg might look noticeably different from the other.

An injury can make those symptoms easier to dismiss. “If you’re worried that you have a DVT, it’s important that you get medical care quickly,” Barnes says. Seek a same-day evaluation through your doctor, urgent care, or an emergency department rather than waiting to see whether it goes away.

Unexplained shortness of breath, chest pain, coughing up blood, or fainting require emergency care because they can signal a pulmonary embolism. A dry cough without a cold, pain when taking a deep breath, or a racing heart can also be clues, says Dr. Stephan Moll, a hematologist and professor of medicine at the University of North Carolina who runs an Athletes and Blood Clots Clinic.

Some pulmonary embolisms cause only mild symptoms—or none at all. People can mistake the discomfort for bronchitis, pneumonia, or a strained muscle, Moll says.

Clots become more common with age. Other risk factors include surgery, injury, prolonged inactivity, cancer, certain inherited conditions, and estrogen-containing medications. But young, active people can develop them, too.

To check for a leg clot, doctors usually use ultrasound. They move a handheld device over the skin to get pictures of the veins underneath, gently pressing as they go. A normal vein should flatten under that pressure.

With a clot, “you can’t squeeze it closed because that solid clot is in the way,” Barnes says.

Doctors typically use a specialized CT scan to look for clots in the lungs. Finding them in both lungs doesn’t, by itself, establish how sick someone is, Barnes says. Doctors also check oxygen levels, blood pressure, and whether the heart is struggling to pump blood through the lungs.

Pulmonary embolisms range from mild cases to medical emergencies, Moll emphasizes. Some people need treatment in the hospital, including medication that dissolves clots or a procedure to remove them. Many others can be treated with anticoagulants, commonly called blood thinners.

Blood thinners help keep clots from growing and prevent new ones from forming. “They do not dissolve blood clots,” Moll says. Your body gradually breaks down the existing clot, though some people are left with scar tissue.

Many people with DVT can take medication at home, Barnes says. Some people with lower-risk pulmonary embolisms can, too.

Treatment for DVT or pulmonary embolisms generally lasts at least three months. “For the first three months it’s uninterrupted blood thinners,” Moll says.

After that, doctors weigh the chance of another clot against the risk of bleeding from continued medication. What caused the clot helps guide that decision. Someone who developed one after surgery may be able to stop once treatment is complete and that temporary risk has passed. “But if this kind of came out of the blue,” Barnes says, longer-term treatment may make sense. Cancer, continued immobility, and certain clotting disorders can also affect the decision.

Having a scan that looks better doesn’t automatically mean it’s time to stop medication, Moll says. Doctors generally follow symptoms rather than ordering repeated scans to watch a clot disappear.

Even someone who stops daily medication may need a prevention plan for future surgery or another period of increased risk. “Risk factors vary, and the length of treatment varies, and the recovery varies,” Moll says.

A blood-clot diagnosis doesn’t necessarily mean you need to stay on the couch.

“I’m not asking them to go for a jog or run a marathon,” Barnes says. “But I want them to be up and walking around as much as they can tolerate,” gradually doing more every day.

Getting tackled is another matter. Blood thinners make bleeding harder to stop, so a collision or fall—especially one involving a head injury—can become much more dangerous. When it comes to contact sports like football, “I would not let an athlete play on blood thinners,” Moll says.

For some athletes who need long-term treatment, specialists may consider a carefully managed, intermittent medication schedule after the initial three months, Moll says. It isn’t suitable for everyone and requires expert oversight; patients shouldn’t skip doses to play sports. Ask your doctor which activities you can safely return to and when.

Keeping your legs moving can also help reduce the risk of future clots. On long flights, Barnes recommends getting up to walk every one to two hours. While you’re seated, pretend your big toe is a pen and trace the alphabet with it to get your ankle moving and help pump blood through your legs. “You can do that just sitting in your seat. Nobody knows,” he says. If you’ve recently had a clot, check with your doctor before flying.

Some people feel much better relatively quickly. Others experience lasting damage to the veins after DVT, which can leave blood struggling to flow back up the leg. That can result in what doctors call post-thrombotic syndrome: “chronic swelling, chronic pain, chronic leg heaviness,” Moll says. After a pulmonary embolisms, some people continue to have shortness of breath, chest discomfort, or fatigue, particularly if the clots haven’t fully cleared.

Depending on what’s causing the symptoms, treatment might include compression stockings for leg swelling, specialized rehabilitation, or a procedure to address damaged veins or lingering clots. Tell your doctor if those symptoms linger. “We have treatments that we can offer to try and make that better,” Barnes says.
