McCreary (knee) was a full participant in Thursday's practice, Jim Wyatt of the Titans' official site reports.
McCreary didn't practice Wednesday due to a knee issue, but that appears to have been a maintenance day as he was able to practice in full Thursday and should be good to go against the Vikings on Sunday. In the five games since Tennessee's Week 5 bye, McCreary has logged 13 tackles (11 solo), including 1.0 sacks, and one pass defense.
