Warner has really evolved his game the past several weeks and stepped up in Kwon Alexander’s absence. He was huge in pass coverage Sunday with two pass breakups. One came in the first quarter while covering wide receiver Marquise Brown, and the second came on a fourth down late in the game against tight end Mark Andrews. He was also good for his usual double-digit tackle total, finishing with 11.
