Treveon Graham has suffered a torn left hamstring and is expected to be out for two months.

Graham signed a two-year deal with the Brooklyn Nets at the veteran's minimum.

DeMarre Carroll will undergo surgery on his right ankle Tuesday and will be out indefinitely.

Kenny Atkinson did not provide a timetable for Carroll's return but told reporters that he did not consider the injury to be serious.

Carroll was Brooklyn's third-leading scorer and second-leading rebounder last season, averaging 13.5 points and 6.6 rebounds per game.

The Brooklyn Nets have exercised the 2019-20 contract options for center Jarrett Allen and guard Caris LeVert.

Allen appeared in 72 games (31 starts) in his rookie season, registering averages of 8.2 points, 5.4 rebounds and 1.2 blocks in 20.0 minutes per game. The 20-year-old was selected by Brooklyn with the 22nd overall pick in the 2017 NBA Draft. 

LeVert has appeared in 128 games (36 starts) in his first two seasons with the Nets, recording averages of 10.4 points, 3.5 rebounds, 3.2 assists and 1.0 steals in 24.2 minutes per contest. During the 2017-18 campaign, the 24-year-old recorded averages of 12.1 points, 3.7 rebounds, 4.2 assists and 1.2 steals in 26.2 minutes per game. LeVert was originally selected with the 20th overall pick in the 2016 NBA Draft by the Indiana Pacers before being acquired by Brooklyn in a trade on July 7, 2016.

The Brooklyn Nets have signed guards Tahjere McCall and Shannon Scott. 

McCall (6’5”, 190) joins Brooklyn after playing last season for the Long Island Nets, Brooklyn’s NBA G League affiliate. In 37 games (31 starts) for Long Island, McCall recorded averages of 9.1 points, 4.5 rebounds, 2.9 assists and 1.8 steals in 28.2 minutes per contest. On the collegiate level, McCall played two seasons at Tennessee State (2015-17) after spending his first two years at Niagara University (2012-14). 

Scott (6’1”, 185) joins the Nets after most recently appearing in seven games with Panteras de Miranda in Venezuela. He also played in 49 games (41 starts) for the Long Island Nets last season, averaging 7.9 points, 4.9 assists and 4.1 rebounds in 28.3 minutes per contest and finishing the year ranked second in the NBA G League in steals per game (2.3). 

The Brooklyn Nets have requested waivers on guard Jordan McLaughlin and forward Nuni Omot.

McLaughlin originally signed as a free agent with the Nets on Aug. 20, while Omot inked a deal with Brooklyn on Sept. 25. McLaughlin and Omot each appeared in the Nets’ preseason game versus the New York Knicks on Oct. 3.

Brooklyn’s roster now stands at 18 players.

The Brooklyn Nets have converted the contract of Theo Pinson into a two-way deal.

Pinson went undrafted in 2018 out of North Carolina.

Shortly after Jahlil Okafor was traded by the Philadelphia 76ers to the Brooklyn Nets, he sat down with a staff member of his new team who helped him realize he might have been dealing with depression and anxiety.

“I didn’t know I was dealing with depression and anxiety myself,” Okafor told The Athletic. “When I was in Brooklyn after the Philly trade, I started to talk to somebody there. That was the first I heard about it. Then, during the season, I didn’t act on it.

“I was in a dark place, man. I didn’t act on what was told to me, and I ignored it and shut it down.”

Okafor appeared in only 26 games for the Nets and before the end of the season, he had an epiphany about his situation.

“A week before the season ended, I looked at myself in the mirror and knew I not only had to get my body right but my mind right,” Okafor said. “I went straight to Miami and changed my diet and worked out. But most importantly, I started talking to a therapist to help me get through the depression and anxiety that I was going through, and it’s something I’m still dealing with. But I’m coping with it a lot better, and I’m learning ways to continue to feel good.

“I thanked Kevin Love because when I was reading his piece, I realized that this is normal and some of the stuff he was talking about … damn, I deal with some of the same things. Kevin Love, we know how successful he’s been in the NBA, but to hear somebody of his stature come out and talk about this is super inspiring to me.

“I lost my mom when I was 9, and it goes way deeper than me playing the game of basketball. It’s my life. It’s my trials. I wouldn’t blame Philly, wouldn’t blame the media or anybody.”

Okafor worked to transform his body and lost 17 pounds over the offseason.

“There was no bullshit with Jah, and I have a no (expletive) approach,” trainer David Alexander said. “We clicked, and it was organic from the beginning. I knew that with Jah, it would be work both mentally and physically. It goes hand in hand. He’s had some unfortunate situations, some setbacks and organizations that weren’t a great fit. I understand the psychological side. With someone like Jah, I understood the space and where he’s coming from. From what I felt and saw, he wouldn’t have benefit from the drill sergeant approach, or the fuck you mentality. The more he believed in himself and his body, the more successful he would be.

“He was extremely inflamed, extremely bloated, when he arrived here to start the offseason program. He wasn’t a fat guy, but he doesn’t have the physique he has now. And when you’re not successful at something you’ve been successful at your whole life, it can eat at you. It can tear you apart. You can’t look at the glass half empty, and I told him he’s got to believe in himself, that he’s young enough to be one of the better big men in this league. He built himself back up.”
