Al Michaels has agreed to join Amazon as their play-by-play announcer for Thursday Night Football. Michaels will sign a three-year deal for a contract worth approximately the same as Joe Buck with ESPN, who signed a five-year, $75 million deal.

Michaels will partner with ESPN's Kirk Herbstreit. 

Michaels will still do a game or two for NBC, including its extra NFL playoff game.

ESPN would have tried to team Michaels with Aikman if Fox declined to let Buck out of his contract.
