Romo had been scheduled to appear in court on Feb. 12 and faced the possibility of six months in jail and a $1,000 fine.
Reports said that Romo, 29, failed to produce the proper identification to clear security at McCarran International Airport and was halted by police. Romo then jawed with a Transportation Security Administration officer and was handcuffed. Reports said that Romo then was taken to the airport police station, cited for violating airport rules and released. He was not allowed to board the flight he was scheduled to take.
Romo soon issued an apology in a statement issued by the Giants.
Romo finished 4-2 with 14 saves and a 1.79 ERA in 69 games for the World Series-champion Giants last year. He also was on the mound for the final out of each postseason round and allowed one earned run in 10 2/3 innings spanning 10 appearances. Romo saved four postseason games, including three in the World Series against Detroit.
