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.
