Romo hit Jesse Holley on a 77-yard completion on the Cowboys' first play of overtime that set up Dan Bailey's winning 19-yard field goal 2 minutes, 53 seconds into the overtime, and Dallas pulled off an improbable, 27-24 victory over the San Francisco 49ers on Sunday.
In one frantic span, Romo emphatically left his mark on the storied Cowboys-49ers rivalry that dates back decades to all those epic matchups in the NFC title game that regularly set up Super Bowl victories by the winner.
"It's got to be one of those things that will follow him through his career. I know what it was here in the locker room at halftime. I know what he had to do to get back on the field," Cowboys owner Jerry Jones said.
"I know what he had to do before [painkillers] took hold to relieve him from his pain. But, boy, did he come back. That was inspirational."
Romo emerged from the locker room after the second-half kickoff and walked briefly into the huddle as Jon Kitna returned to the sideline, then Romo immediately came off under doctor's orders and headed back to the locker room.
Back on the sideline late in the third quarter, Romo tapped Jason Garrett on the shoulder and told the coach to put him back in the game.
Bailey kicked a tying 48-yard field goal Sunday as time expired in regulation. Romo completed 5 of 6 passes on the tying drive, connecting on consecutive throws to Holley before finding him again in OT.
