He played college football for the University of Southern California.

The next year he posted 2,223 passing yards with 18 touchdowns and 6 interceptions.
He helped beat Ohio State University 17-16, after it entered the 1980 Rose Bowl as the number one ranked team in the nation.
Cleveland Browns
McDonald was selected by the Cleveland Browns in the fourth round (109th overall) of the 1980 NFL Draft. He replaced Brian Sipe (who was suffering from a sore throwing arm) in the last three games of the strike-shortened 1982 season, posting a 2-1 record and helping the team make the playoffs that had been expanded to 16 teams.
He started in the first round of the playoffs, a 10-27 loss against the Oakland Raiders, after throwing for 281 yards and 2 touchdowns with no interceptions. In 1984, the Browns did not re-sign Sipe and gave the starting job to McDonald, who posted a 5-11 record after registering 3,472 passing yards, 14 touchdowns and 23 interceptions.
In 1985, he lost his starting job to first round draft choice Bernie Kosar and was eventually waived on June 26, 1986.
He left after passing for 5,269 yards, 24 touchdowns and 37 interceptions. Seattle Seahawks
On July 16, 1986, he signed as a free agent with the Seattle Seahawks. He was released on August 26.
Dallas Cowboys
On November 4, 1986, he was signed by the Dallas Cowboys as a free agent to be the third-string quarterback, after starter Danny White suffered a broken right wrist during the 17-14 loss against the New York Giants.
He became the first left hander quarterback to make the team in franchise history. In 1987, he beat rookie Kevin Sweeney for the third-string quarterback job during training camp.
After the players went on a strike on the third week of the season, those games were canceled (reducing the 16 game season to 15) and the NFL decided that the games would be played with replacement players. Sweeney was signed to be a part of the Dallas Cowboys replacement team, had success and was kept on the roster for the rest of the year along with McDonald.
He was released after never playing a down on August 23, 1988.
