Colts will face Lions without Zbikowski

Colts strong safety Tom Zbikowski is not a real strength in pass coverage for the team.

Now he’s out of Sunday’s game in Detroit because of a knee injury. Bruce Arians said both Joe Lefeged and Sergio Brown will see time in place of Zbikowski.

Brown's most notable moment this season came as he put his hands to his helmet in a what-did-I-just-do reaction after he got beat by Cecil Shorts on an 80-yard catch and run on Sept. 23 that won a 22-17 game for Jacksonville at Lucas Oil Stadium.

Pro Football Focus rates Zbikowski 58th among safeties who’ve seen enough work to qualify, with a 1.7 rating in pass coverage and a minus-4.1 in run defense.

By their count, Zbikowski has played 693 snaps (with 393 in pass coverage), Brown 25 and Lefeged 11

The Colts rank 19th in the NFL in pass defense, which is based on yardage. Detroit fields the league’s top passing offense.

It’s a bad matchup with Indianapolis even at full strength.
