Pierce "feeling good" in Harbaugh's words, but status of knee unknown

The only apparent injury concern to come out of the Ravens’ 38-35 double-overtime win over Denver on Saturday night was running back Bernard Pierce, who continues to deal with a sore knee.
The rookie carried the ball only five times for 14 times after rushing for a game-high 103 yards in the wild-card round win over the Indianapolis Colts. Pierce took only 16 offensive snaps and last carried the ball roughly midway through the third quarter before failing to finish the game.
Coach John Harbaugh would not address Pierce’s knee specifically when asked how the backup running back was feeling on Monday.
“He seems like he is feeling good,” Harbaugh said as he smiled. “He was in good spirits. He had a big smile on his face. He had a nice big lunch today. He seemed like he was happy. His son is doing well. His son slept well last night. I think his son slept through the whole night last night, so he was happy.”
The first injury report of the week will be released on Wednesday afternoon and based on Harbaugh’s comments, it will be the only tangible information we can expect regarding the Ravens’ overall state of health heading into the AFC Championship game.
