49ers placing Trent Brown on injured reserve with shoulder injury

Head coach Kyle Shanahan announced on Friday that right tackle Trent Brown will be placed on injured reserve to end his season. Zane Beadles will start in his place this Sunday against the Tennessee Titans.

Shanahan said he believes it is a labrum issue, but could not provide the specifics. He said it is a five-to-six month recovery window. That would get him back to 100 percent in May or June if the timeline holds up. Brown suffered the shoulder injury in practice leading up to Week 12 against the Seattle Seahawks. He was inactive that week, but played the next week against the Chicago Bears. The injury was not quite right and he was inactive in Week 14 against the Houston Texans.

The 49ers had until 1:00 p.m. PT to make the move today, and if they didn’t get it in by then, they would make the move on Saturday by 1:00 p.m. The 49ers will likely promote one of their three offensive linemen from the practice squad. That group includes Cameron Hunt, Andrew Lauderdale, and Pace Murphy.

Shanahan was asked if he was at all disappointed that Brown wasn’t able to play through the injury. He said he was not disappointed in Brown, just disappointed that the injury will prevent him from playing the final three games. He said he thinks Brown has a chance to be a dominate tackle in the NFL, and wants to get him back healthy.
