Miami Dolphins wide receiver Grant DuBose was hospitalized overnight after suffering a helmet-to-helmet blow during Sunday’s game against the Houston Texans, the Dolphins said Monday.

DuBose attempted to make a catch in the third quarter but was hit in the head by Texans rookie Calen Bullock before his head hit the ground hard. According to NFL.com, DuBose appeared to clench his fists after the hit, demonstrating the “fencing response,” a common movement following a traumatic brain injury. He then remained motionless for over ten minutes while emergency medical personnel rushed to treat him.

They cut off his jersey and put a neck brace on him before placing DuBose on a spineboard with his arms and legs strapped down. A tube could be seen in his mouth and he appeared motionless as he was rolled off the field on a stretcher.

Bullock received a flag for unnecessary roughness for hitting a defenseless receiver on the play.

After being sidelined with a head injury, DuBose remained overnight at a local hospital in Houston for evaluation, the Dolphins said Monday. He has mobility in all extremities and initial tests have shown positive results, but he remains under medical care for further observation.

During his treatment on the field, the Dolphins knelt in a circle and appeared to be praying. Miami head coach Mike McDaniel and Houston head coach DeMeco Ryans hugged while DuBose was still on the ground.

“I just feel bad that I even put him in the situation where he got hit,” Dolphins quarterback Tua Tagovailoa said at a postgame news conference. “It was hard to move on, you know, after that happened.”

The team lost 20-12 to the Texans.

This was DuBose’s first game since suffering a shoulder injury earlier in the season. He was a seventh-round pick last season.
