49ers roundup: Kurtis Rourke taken to hospital for rib injury concern, Nate Hobbs exits with groin issue

San Francisco’s preseason opener came with immediate injury questions, as head coach Kyle Shanahan offered updates on several players after the game. The most serious development involved quarterback Kurtis Rourke, who Shanahan said went to the hospital after he left with a rib injury and was reportedly struggling to breathe.

Shanahan’s remarks framed the situation as ongoing and not yet fully clarified. He indicated he did not want to go too deeply into details because there were not fresh updates at the time, a sign the medical information was still being sorted. That matters in the preseason, where teams try to balance evaluation with avoiding deeper risk to players who are still fighting for roles.

Alongside Rourke’s situation, Shanahan also addressed other exits during the contest. Cornerback Nate Hobbs was pulled from the game with a groin injury, leaving the defensive staff to consider how much of his workload can be managed in the short window of preseason practice and competition.

The 49ers’ injury list also included wideout or defensive-skill usage changes tied to Marques Sigle. Shanahan said Sigle has an oblique injury, an issue that can affect upper-body rotation and core stability. In preseason games, that type of ailment can limit route precision, timing, and overall conditioning even if a player returns later in the week.

Preseason injury updates often have a downstream effect beyond the player who exits early. For the 49ers, the immediate consequence is depth and next-rep planning, because quarterback reps and secondary snaps tend to be heavily managed. If Rourke’s rib injury becomes more than a short-term concern, the team’s remaining quarterback evaluation path could tighten quickly, especially if other players are already moving through scripted packages and snap limits.

On the defensive side, Hobbs’ groin issue carries a similar practical problem. Groin injuries can linger, and even when a player is listed as “day-to-day,” teams frequently scale back cutting, press coverage bursts, and special-teams responsibility while reassessing. That can open opportunities for backups to take more first-team reps and can also influence how aggressively the staff schemes around matchups.

What to watch next is whether Shanahan and the team can provide clearer medical timelines after the initial reports. While preseason injuries are common, the combination of a quarterback leaving for a hospital visit and the staff saying it lacks additional updates immediately suggests the 49ers will prioritize follow-up evaluations before making decisions about snap volume and practice participation.

Until more is confirmed, the safest takeaway is that San Francisco is dealing with at least three separate ailments across multiple positional groups after its first preseason game. The 49ers will likely use the next set of practices to recalibrate reps, monitor conditioning, and determine whether any of these players can return quickly or need additional time. For fans and roster followers, those decisions will shape the early formation of the depth chart going into the later preseason window.
