Adrian Colbert

As part of our training camp countdown, we profile 49ers free safety Adrian Colbert and assistant defensive backs coach Daniel Bullocks.

Marquise Goodwin ended his mercurial season on and off the field, with a head injury. However, the 49ers said that Goodwin will be OK after going to the hospital for observation.

You could argue the 49ers have been the most injured team in the league this year. Against the Titans, the team placed two players into the concussion protocol.

The placement of right tackle Trenton Brown on season-ending injured reserve dominated the injury news. However, the 49ers might also be short at cornerback against the Titans on Sunday.

Jimmy Garoppolo’s leadership extents to the entire team. He proved that in Houston when the defense listen to him about playing with violence.

This 49ers team is relishing their wins like no other. The post-game locker room seems to dissolve into delirium after wins and players are getting fired up by blaring hip-hop from a huge boom box, that was started by right tackle Trent Brown against the Giants.

In a mild surprise, right tackle Trenton Brown will not play, which could mean Jadaveon Clowney could be getting after quarterback Jimmy Garoppolo.

The 49ers have struggled with depth issues along the defensive line this season, and on Friday, head coach Kyle Shanahan confirmed that the unit would be receiving a reinforcement this weekend.

In what must be an NFL record, three 49ers’ safeties have broken bones in each of the last three games.

49ers safety Adrian Colbert is a player to watch for the rest of the season after he returns from surgery on his broken thumb.
