Carson landed on IR before Week 1 with a hyperextended knee, but returned to practice as soon as he was eligible at the beginning of October. He has been a full participant in practice for the last two weeks and should be full-go on Sunday. Carson's activation comes at a crucial time for the Cowboys. Their defense has allowed the most passing yards per attempt and per game to opposing offenses this year, and they will be without starting cornerback Trevon Diggs this week.
