There was no official notification of Thompson’s injury, but doctors and athletic trainers looked to be inspecting his ribs after he was shoved down following a pass midway through the quarter.

While it was the shove from Dre’Mont Jones on a seemingly innocent play that sent Thompson to the sideline, the injury might have been inflicted on Miami’s previous possession when he was sacked by Tyrell Dodson.

Thompson was sluggish to get up following the collision from Dodson and was somewhat slumped over at the midsection as he raced off the field. He returned for the next series, but stayed down for several minutes after completing a pass to De’Von Achane. Thompson remained on his back for a few minutes before rising up and went immediately to the locker room.

He was replaced by Tim Boyle as quarterback.

The incident to Thompson came a little over a week after Tua Tagovailoa sustained his third concussion in the past two years in a defeat to Buffalo. Tagovailoa was placed on injured reserve earlier this week.

It was the third severe injury suffered by the Dolphins in the game after left lineman Terron Armstead (eye) and cornerback Kendall Fuller (concussion) were injured in the first half.

Fuller suffered a concussion during the first quarter and after being checked was declared out early in the second half. Armstead’s injury was reported late in the second quarter and Kendall Lamm stepped in as his replacement.

Seattle lost major depth on their defensive line with injuries to Byron Murphy II and Leonard Williams in the first half.

Williams got hurt on the opening series and walked to the locker room holding his abdomen. He appeared prepared to return in the second quarter but was finally held out.

Murphy was hurt midway through the second quarter during an 8-yard run play for the Dolphins. Murphy walked slowly to the changing room before being declared out.
