At the midpoint of the season, the Ravens were excited about the potential of their trio of young tight ends.
But in a season full of injuries, even that group is now dwindling.
Starting tight end Crockett Gillmore left early in Sunday's game against Miami with a back injury. He was immediately ruled out for the remainder of the game.
Head Coach John Harbaugh did not have an update on his condition after the game.
"I don't recall the exact play that it was on," Harbaugh said. "I just know he was out for the rest of the game."
Gillmore seemed to suffer the injury at the end of a 7-yard catch in the first quarter. He was hit hard in the back by Dolphins linebacker Koa Misi as he tried to fight for extra yardage.
With rookie second-round tight end Maxx Williams already scratched due to a concussion, that meant the Ravens had just one tight end, rookie fifth-round pick Nick Boyle, for the majority of the game.
Boyle finished with three catches for 15 yards.
The Ravens' young tight end trio has been banged up this season. Gillmore missed two games earlier this year with a calf injury and Williams has now missed two contests. Boyle was sidelined for one by a foot injury.
Baltimore's offense is also without starting quarterback Joe Flacco (knee), No. 1 wide receiver Steve Smith Sr. (Achilles), starting running back Justin Forsett (broken arm), starting left tackle Eugene Monroe (shoulder) and starting center Jeremy Zuttah (shoulder).
