NESN's Doug Kyed initially reported the news, adding the injuries are serious but not considered life-threatening.
"They are hurt but they are alive and that's a blessing we are grateful for," said Langi's father-in-law, Rick Wahlin, per Dick Harmon of DesertNews.com.
"They were taken to two separate hospitals, and we are trying to get both of them at the same facility so they can recover together," Wahlin said.
Harmon also provided details of the accident and the injuries:
"Emergency crews had to cut the top of Langi's car to extract him and his wife after a vehicle traveling at a high rate of speed hit the back of Langi's car, which had stopped to make a left turn into their apartment parking lot on Fisher Street. The collision pushed Langi's car into two other vehicles that were in front of their vehicle.
"Langi is being treated for neck and head injuries, and his wife, Cassie, suffered fractures to both hips, broken ribs and is being evaluated for possible internal bleeding and injury to her liver and spleen, according to Wahlin...
"Wahlin said firefighters had to use the 'Jaws of Life' to cut into Langi's vehicle to remove them to emergency vehicles. 'They are torn up but very lucky to be alive. All Harvey has cared about is how Cassie is doing, that's been his biggest concern, and we are grateful for him and all the prayers that have been directed toward our families.'"
Patriots practice-squad safety David Jones was among those who tweeted well-wishes upon hearing the news:
An undrafted free agent out of BYU, Langi signed with the Patriots in May and secured a spot on the defending champions' 53-man roster.
Langi has appeared in one game, a 36-20 Week 2 win over the New Orleans Saints. He has yet to log a tackle.
