San Francisco 49ers rookie punter Bradley Pinion suffered a calf injury on Sunday during the team's loss to the St. Louis Rams.

Matt Barrows of the Sacramento Bee is reporting that Pinion says the calf injury is to his kicking leg, but he'll be "ready to roll" for Sunday's home game against the Atlanta Falcons.

Pinion has a net average of 40.7 yards-per-punt this season with 14 punts inside the 20-yard line. His longest was a 60-yard punt.
