The 26-year-old TE exited the game due to the injury, and was taken to the hospital as a precaution. Well, it may be good that they took him in, as it turned out Higbee had a lung injury which caused him to cough up blood, per Ian Rapoport.
Fortunately, the expectation is that Higbee will only miss a short amount of time, if he's sidelined at all.
Obviously coughing up blood is incredibly worrisome, but he was taken to the hospital and received the treatment he needs, and it doesn't seem like it will be a huge issue going forward.
Higbee just recently signed an extension with the Rams, keeping him in Los Angeles through the 2023 season. While he's not a huge factor in the passing attack, he's a capable pass catcher and an effective blocker.
Hopefully he'll be good to go for Week 3's clash with the Cleveland Browns.
