Wall dedicated Washington's 133-132 double-overtime victory over Boston to Telemaque-Nelson, who passed away earlier Monday after a battle with Burkitt's Lymphoma.
"This is an emotional game for me," Wall told CSN Washington's Chris Miller after the game. "This is for Miyah, one of my closest friends I lost. I met [her] last year. It's just tough. To see a little kid that fights so hard [against] cancer and can't beat it. This game is for her. My jersey, my shorts, I'm going to give it to her family. It's a tough day for me. I was really quiet today."
As the interview progressed, Wall fought back tears and bent over as he tried to regain his composure.
Following the game, Wall posted an extended message about Telemaque-Nelson, along with some photos of the two of them together, on Twitter.
"If you were blessed to meet and get to know Miyah you know how special of a little girl she was," he wrote. "I'm saddened by the news but I know that she's in a better place. Keep her family in your prayers. I'll definitely miss my buddy. Rest In Peace Miyah."
The Wizards held a pregame moment of silence for Telemaque-Nelson, who first met Wall in March. Wall then launched a social media campaign to help Telemaque-Nelson meet rapper and singer Nicki Minaj.
“I knew [Minaj] had a caring heart, and when she had an opportunity to see it or read about it, I knew she’d reach out as soon as she could,” Wall told the Washington Post back in March. “I just thank my fans, everybody who retweeted it and reposted it, to give me the opportunity to make this girl’s wish come true. And we’ll try to make it happen.”
CSNWashington.com notes that Wall, 24, has also been writing Telemaque-Nelson's name on his shoes throughout the 2014-15 season as a tribute.
Wall finished with 26 points (on 10-for-17 shooting), a career-high 17 assists and seven rebounds on Monday. He scored Washington's final 10 points in the second overtime period, including the game-winning and-one basket with 44 seconds remaining.
