Dodson, fighting at 125 pounds, landed left hands twice in the second round, sending Johnson to the ground. In the third round, Johnson had a takedown and landed a knee to get back in the fight. Johnson was warned after two illegal knees, a low blow in the first round and an illegal knee in the fourth round.
Johnson (17-2-1) started taking control late in fourth land, landing a series of knees to Dodson's head and a series of punches as Dodson (15-6) tired. It continued in the fifth and final round, as Dodson couldn't defend repeated knees to his head.
Johnson struggled in the first two rounds.
"I got dazed a little bit, but I am in good shape," Johnson said. "It is going to happen. You are going to get hit."
In what may have been the most anticipated fight of the night, Glover Teixeira topped Rampage Jackson in a unanimous decision in a light heavyweight bout.
Jackson, the 34-year-old former light heavyweight champion was taken down in all three rounds, but Teixeira (20-2) couldn't take advantage. Jackson (32-11) got back to his feet every time. Late in the second round, both fighters exchanged blows. Jackson tried to shrug off Teixeira's punches, but fatigue appeared to be setting in.
The fight was scored 30-27, 30-27, 29-28.
Jackson, who fought his last fight under his current UFC contract, has been critical of the UFC and how he perceives the organization treats its fighters. He insists the fight was his last in the UFC, but plans on continuing his MMA career.

Thomas comments on steroid era
Retired Chicago White Sox slugger Frank Thomas feels even better about his career after watching steroids-tainted stars Barry Bonds, Sammy Sosa and Roger Clemens fail to gain entry to the Hall of Fame.
"I think I've done enough to be a first-ballot Hall of Famer," he said Saturday at the team's fan convention.
"Watching all the nonsense unfold and not really knowing what was going on, it makes me much more proud of my career," he said. "I competed in that era. I played at a high level in that era. There are a lot of great players, but as it unfolds, a lot of it was not the real deal. I know 100% I was the real deal."
Bonds, Sosa and Clemens were denied in their first year of eligibility amid suspicions by some voters that their accomplishments were boosted by performance-enhancing drugs. Mark McGwire, 10th on the career home run list, received 16.9% of the vote on his seventh try, far short of the 75% needed for election.
"I wouldn't say I feel bad for them," Thomas said. "I respected them on the field, but they chose this. They made their own decisions off the field and they've got to live with it."
A person familiar with the negotiations said pitcher Jhoulys Chacin and the Colorado Rockies have agreed to a $6.5-million, two-year contract.
The person spoke on condition of anonymity because the agreement is subject to a physical.
Chacin had asked for $2.6 million in arbitration and had been offered $1.7 million by the Rockies. The 25-year-old right-hander was eligible for arbitration for the first time after going 3-5 with a 4.43 ERA in 14 starts last year, when he missed more than three months because of right shoulder inflammation. He made $482,000.
The 6-foot-8 White, the 16th overall pick in the last draft, has been on the inactive list all season as he worked on an arrangement with the team to balance his acknowledged anxiety disorder with the demands of the NBA schedule.
Lindsey Vonn showed she can beat Tina Maze in the Slovenian's best discipline and on her home snow.
Though it may be too late to challenge her biggest rival for the overall World Cup title, Vonn is looking like Maze's biggest challenger at next month's world championships.
The American proved that she has fully recovered from a recent illness by winning a World Cup giant slalom at Maribor, Slovenia, her second win in two weeks.
Vonn was third behind Maze after the first run but overcame several errors in the second to put down the fastest time. Vonn won in 2 minutes 22.2 seconds for her first GS victory since last March.
Maze still clinched her third giant slalom discipline title by placing second. Maze had a near-perfect first run, but a poor start to the second cost her valuable time and she finished 0.08 seconds behind Vonn.
With her 59th World Cup win overall, Vonn's just three away from equaling Annemarie Moser Proell's record on the women's side.
Dominik Paris of Italy won the classic World Cup downhill in Kitzbuehel, Austria. American Ted Ligety missed a gate and failed to finish.
