49ers left guard Mike Iupati was seen wearing a brace on his left knee after being carted off during Sunday’s loss to the Saints.
Cornerback Tarell Brown was in a lot of discomfort after suffering a rib injury, according to CSNBayArea.com.
Coach Jim Harbaugh said he had no official updates on the conditions of Iupati and Brown.
Veteran Adam Snyder entered the game in the third quarter when Iupati was injured on a running play when Frank Gore rolled onto his leg while being tackled by Saints nose tackle Brodrick Bunkley.
Brown was injured late in the second quarter while he made a tackle of New Orleans running back Pierre Thomas at the goal line. While Brown was making the tackle he appeared to sustain the injury from a knee of a Saints player.
