49ers' Trenton Cannon Taken Off Field in Ambulance After Injury vs. Seahawks

San Francisco 49ers running back Trenton Cannon suffered a scary injury during the opening kickoff of Sunday's game against the Seattle Seahawks.

Albert Breer of Sports Illustrated stated that Cannon "got his head bent back" during the play. Cannon was placed on a stretcher and taken off the field in an ambulance and is out for the game with a concussion, per NBC Sports' Matt Maiocco. Maiocco also reported that he saw Cannon's left arm moving.

The 49ers later told reporters Cannon is in stable condition and will remain in the hospital overnight for observation.

During the play, Cannon was attempting to tackle Seahawks kick returner DeeJay Dallas and as he dove, he ran into one of his own teammates.

Cannon is in his first year with the 49ers after being claimed when the Baltimore Ravens waived him in September. The four-year veteran has spent most of his time on special teams this season. In 10 games, he's had 16 kickoff returns for 328 yards, but he hasn't reached the end zone. He's also registered eight tackles.

A sixth-round pick in the 2018 NFL draft, Cannon started his career with the New York Jets. The Virginia State product rushed for 113 yards and one touchdown to go with 17 catches for 144 yards as a rookie. Cannon spent the majority of the 2019 season on injured reserve and was waived. The Carolina Panthers picked him up prior to the 2020 season and waived him a year later.

San Francisco has had trouble staying healthy this season. Wide receiver Deebo Samuel (groin), running back Trey Sermon (ankle) and defensive lineman Maurice Hurst (calf) were all ruled out for Sunday's game. Samuel leads the team with 1,006 receiving yards and five touchdowns, adding four touchdowns on the ground. His groin strain is expected to keep him out for one to two weeks.

At 6-5, the 49ers are fighting to maintain their position in the NFC playoff picture.
