Left tackle Bryant McKinnie won't be seeing double when he lines up in his customary spot in the Ravens' home game against the San Francisco 49ers on Thanksgiving night.
The 49ers' starting right defensive end is Justin Smith, and their backup right outside linebacker is Aldon Smith.
Justin Smith is an 11-year veteran who ranks third on the defense with 4½ sacks this season. Aldon Smith is a first-round pick in April who leads the team 7½ sacks thus far.
McKinnie will likely see a lot of both players Thursday night.
"I'm familiar with Justin from playing San Fran before when I was in the NFC [with the Minnesota Vikings]," McKinnie said. "And when he was in Cincinnati, I played against him. He's definitely gotten a lot better these past few years. He's a tough player. The rookie, I'm still learning about him. I see he has good pass-rush moves. They're two pretty good players."
