Colts declared CB Vontae Davis (knee) active for Sunday's game against the Lions.

After missing four straight games, Davis returns and joins Cassius Vaughn in the starting lineup. Struggling Darius Butler will be the third corner. The Colts are expected to "play sides" with Calvin Johnson instead of shadowing him. TE Coby Fleener (shoulder) is also active, as expected. The Colts' inactives: WR Palmer, S Tom Zbikowski, RB Robert Hughes, TE Dominique Jones, T Bradley Sowell, G Tony Hills and DT Kellen Heard.

Colts CB Vontae Davis (knee) is listed as doubtful for Week 12 after missing Friday's practice.

Davis practiced Wednesday, couldn't make it through a full workout on Thursday, and was held out entirely on Friday. So he's not going to play against the Bills. The Colts will continue to start Cassius Vaughn opposite Darius Butler. Josh Gordy will be the nickel back for Indianapolis' injury-riddled back end.

Colts CB Vontae Davis (knee) has been ruled out for Week 11.

According to beat writer Mike Chappell, Davis might finally be ready to return in Week 12. With Jerraud Powers landing on injured reserve Monday, the Colts will likely be forced to go with Darius Butler and Cassius Vaughn at corner against the Patriots' high-powered passing attack. It's going to be a long afternoon for the Horseshoe.
