Sherman suffered a mild calf strain, according to Rapoport.
Also providing an update was Jordan Schultz of ESPN.
Sherman needed assistance to get off of the football field at halftime during Sunday's loss to the Kansas City Chiefs at Arrowhead Stadium. Head coach Kyle Shanahan told reporters after the game that it was a calf injury but did not have any information beyond that.
Sherman has been targeted by opposing quarterbacks six times in his first season with the 49ers and given up just one reception for 18 yards, according to Pro Football Focus. Quarterbacks have a passer rating of 39.6 while targeting Sherman.
While no injury is good news, fans have to be relieved that the injury is unrelated to Sherman's Achilles injury suffered last November. Sherman will be back on the field for the 49ers this season.
