Isaac Guerendo, running back for the San Francisco 49ers, is dealing with a foot and a new hamstring injury, which has kept him from practicing on Wednesday. He managed to play through the foot issue last Thursday, but his availability for the upcoming game against the Dolphins is now in question. If Guerendo is unable to play, Patrick Taylor is expected to step in as the lead back for the 49ers.

• Isaac Guerendo's injury status is uncertain for the upcoming game against the Dolphins.
• Patrick Taylor is poised to take over as the lead back if Guerendo cannot play.
