28-year-old Dawson has recently recovered from a four-month absence with an Achilles injury and featured during Spurs' FA Cup win over Cheltenham Town at the weekend.
"I was out for three months last year and I then went out to play lots of games so it's not the first time this has happened," Dawson said.
"Injuries are hard and when you come back you need to come back and perform at the best of your ability and do what you can and I will always back myself to do that.
"I didn't feel any reaction to the injury [on Saturday]. I feel good.
Dawson joined Spurs in 2005 from Nottingham Forest.
