Horford dislocated the pinkie finger on his right hand during the Hawks' 99-92 victory over the Nets in Game 1. Despite leaving the court immediately after suffering the injury, Horford did return with just under six minutes left in the game, but missed both of his shots.
During that match, Horford scored 10 points, grabbed 10 rebounds, dished out two assists and blocked one shot.
"It's sore," Horford told ESPN. "I've just been doing a lot of treatment on it last night and this morning."
Horford also thanked his wife for providing him with ice and Epsom salts after the game.
"I've been able to deal with pain and soreness and stuff like that, but to me it's just the taping, the mechanics of it, because the way that I shoot the ball, it kind of disrupts how I grab the ball," Horford said. "I just have to get used to it. With the coaches today, I worked on shooting and getting a feel for having my fingers taped."
Meanwhile, Hawks head coach Mike Budenholzer made it clear that no hasty decisions will be made, especially since Horford is a pivotal part of the team's line-up.
"We'll see how he kind of makes progress today and again tomorrow," Budenholzer said. "We'll see what he can do in practice and kind of continue to monitor him and hope for the best."
