Lennon took himself off towards the end of the 1-0 home defeat by Stoke with an ankle injury despite being asked to play on by Redknapp, which left Spurs with only 10 men and saw the visitors score a late goal to clinch victory.
Redknapp was keen to play down any talk of a rift with Lennon over his injury.
"It's been blown out of proportion," he said. "I am not disputing that Aaron was injured. He will have a scan today to see what damage he has done to his ankle. I wouldn't have wanted him to do more damage by staying on."
