SANTA CLARA, Calif. -- After suffering a rib injury in Sunday's loss to the Dallas Cowboys, San Francisco 49ers linebacker Reuben Foster wasn't quite sure how he would feel as the week went on, and thus also wasn't certain about his status for this week's game against the Philadelphia Eagles.
Niners coach Kyle Shanahan was cautiously optimistic Foster would be ready to go, but also acknowledged the Niners medical staff would need to see how Foster felt when he woke up Monday.
Given that time to recover and evaluate Foster's status, all signs point to him being ready to play in back-to-back regular-season games for the first time in his young career.
"[Reuben is] all right," Shanahan said. "He should be good to go. We’ll recheck it tomorrow. But, he was real sore today. MRI and the X-rays were OK, or negative.”
That's good news for Foster, who missed all but 11 snaps in the first six games with a high ankle sprain. He finally returned against Dallas but suffered a rib injury in the second half. Initially, the injury kept him on the sideline for only one play before he returned. A handful of plays later, Foster aggravated the injury and came out again.
Although Foster was cleared to return, Shanahan decided to hold him out the rest of the game as the Niners were facing a huge deficit. Foster made five tackles, including one for loss, before departing.
After missing so much time, Shanahan said Foster was in charge of the defense from his middle linebacker spot and seemed to handle it well after his review of the game tape.
“He ran everything," Shanahan said. "He was the MIKE linebacker out there. So, he made all the calls. For his first NFL game, not counting I think the 10 plays he had versus Carolina, I thought he did a pretty good job. He got our guys lined up fast every time. I think he'll get better as we go. I think he'll learn from a lot of stuff he did miss, but I think for his first game out there, I thought he did a good job.”
Elsewhere on the injury front, the Niners will have some things to monitor as the week goes on. Nickel cornerback K'Waun Williams suffered a quadriceps injury that Shanahan said makes Williams unlikely to play this week. Right tackle Trent Brown is in the concussion protocol and the Niners will also keep an eye on him as the week goes on.
Finally, guard Brandon Fusco is battling a biceps injury that Shanahan said will make him questionable this week. If Fusco can't play, the Niners will have to choose between veteran Zane Beadles and rookie Erik Magnuson to fill in.
"We probably won't know that all week," Shanahan said. "I know he's got a chance. But that's going to be -- we'll have to see how he recovers from rehab throughout the week, but he does have a chance."
