The Titans haven’t played since Sept. 27. They have barely practiced.
It hasn’t mattered so far tonight.
The 3-0 Titans have looked better than the 4-0 Bills and lead 21-10 at halftime.
Brown, who is returning from a knee injury that has kept him out since Week One, has four catches for 55 yards and the score.
Tannehill also ran for a 10-yard score.
Josh Allen is 10-of-21 for 124 yards with a touchdown and an interception. His touchdown went to Isaiah McKenzie and covered 3 yards.
Titans left tackle Taylor Lewan exited in the first half with a right shoulder injury. The team lists him as questionable to return.
Titans running back Darrynton Evans (hamstring) also is questionable to return.
