The Celtics locked up forward Jaylen Brown on Monday, signing him to a four-year contract extension worth up to $115 million.
Per The Boston Globe, Brown is guaranteed $103 million with his new deal, including an additional $12 million based on incentives.
Boston had until 6 pm ET on Monday to sign Brown to a rookie-scale contract extension. If they hadn't, Brown would've been a restricted free agent next offseason.
Brown, the number-three overall pick in 2016, averaged 13 points and 4.2 rebounds per game last season.
"Jaylen has made tremendous strides over the last three years and has become a fantastic player for us on both ends of the court,” said Celtics president of basketball operations Danny Ainge. "He’s a great person and hard worker who, at 22 years old, can score and defend against the best players in the NBA.
“Jaylen is a true professional who did a great job accepting his role last season, and he is a major part of our championship goals.”
