NASHVILLE, Tenn. — Rob Bironas kicked a 46-yard field goal in overtime, and the Tennessee Titans beat the Miami Dolphins 27-24 Sunday after blowing an 18-point lead.

Tennessee kept alive faint playoff hopes for another week.

Vince Young threw for a career-high three touchdowns, Chris Johnson ran for 104 yards as the Titans (7-7) reached .500 for the first time this year. But the Titans made it far too interesting by blowing the big lead.

The Dolphins (7-7) also viewed this as an elimination game for their own playoff hopes. They trailed 24-6 in the third quarter before rallying, tying on Ricky Williams' 2-point conversion run with 1:34 left.

Miami won the toss and got the ball first in overtime. But Michael Griffin picked off Chad Henne's pass, and Bironas kicked the winner four plays later.
