Doyle's injury required hospitalization, but the team expects the sixth-year pass-catcher to be released soon. The 28-year-old was hurt after taking a big hit in the fourth quarter.
The loss of Doyle leaves Eric Ebron as the team's unquestioned top tight end. That was already true on paper with the free-agent addition ranking second on the roster with 44 catches for 508 yards and 11 touchdowns.
Doyle posted 26 grabs for 245 yards and two scores, but also served as a reliable blocker. His loss puts pressure on a banged-up position group, shifting Mo Alie-Cox -- who missed Sunday's game with a calf injury -- into a more prominent role ahead of Erik Swoope, who also sat out because of a knee injury.
