The Miami Dolphins' problems continued on Sunday with a 24-3 loss to the Seattle Seahawks, which was further marred by injuries to key players, including quarterback Skylar Thompson and left tackle Terron Armstead.

Thompson, who was starting in place of Tua Tagovailoa — who is on the injured list and will miss at least three more games with a concussion — was knocked out in the third quarter. Seahawks defensive end Dre'Mont Jones hit Thompson as he completed a pass to running back De'Von Achane. Thompson, who appeared to be clutching his chest after the hit, was escorted to the locker room and did not return.

“He (Thompson) has a rib injury. We'll know more tomorrow,” Dolphins head coach Mike McDaniel said in his post-game press conference on Sunday.

Substitute Tim Boyle stepped in for Thompson, while newly signed Tyler Huntley was designated as the third emergency quarterback but was not used.

Thompson completed 13 of 19 passes for 107 yards before being eliminated, but the Dolphins offense managed just one field goal. Penalties and poor play from the offensive line hampered Miami's efforts.

“I'm not making excuses,” McDaniel added. “I thought both quarterbacks had good control of the ball, but we just didn't execute.”

Armstead's injury is another example of Miami's offensive problems.

The Pro Bowl left tackle, who had been struggling with shoulder problems since Week 2, had to leave the field with an eye injury in the third quarter after a collision at the line of scrimmage and did not return.

Dolphins tackle Kendall Lamm replaced Armstead and rookie offensive tackle Patrick Paul made his NFL debut in the fourth quarter when Lamm moved from left tackle to right tackle to replace Austin Jackson, who was briefly out with an unspecified injury before returning.

In addition to the absences of Thompson and Armstead, linebacker David Long Jr. left the game with a hamstring injury and fullback Alec Ingold was briefly treated in the medical tent.

McDaniel did not provide an update on Long and Ingold's injuries, but confirmed that Armstead and cornerback Kendall Fuller are in concussion protocol.

The Dolphins played the game without injured running back Raheem Mostert (chest) and rookie wide receiver Malik Washington (quad).

With a record of 1-2, the Dolphins have an extra day to rest as they prepare to host the Tennessee Titans (0-3) on Monday Night Football in Week 4.

As the number of injuries continues to rise, the team must now find a way to quickly regroup in order to turn the season around.
