Celtics’ rookie Robert Williams missed his second summer league game in a row; however, this time is not due to oversleeping, as it happened with his introductory media conference call. The Boston Celtics have decided to give him some rest after a knee contusion he suffered in his first game, which aggravated an artery condition in his legs.

The former A&M Texas center got picked No. 27 overall by Boston this NBA draft, after averaging 11.1 points and 8.7 rebounds in 61 games over two collegiate seasons where he consolidated as an outstanding defensive player, winning twice the "Defensive player of the year" in the Southeastern Conference. Not to mention his 78 blocked shots as a sophomore, which stands as the second-most by an Aggie in a single season. Nevertheless, he started with the wrong foot in his professional career; beginning with a missed first-media-call due to oversleeping, followed by not attending to the first team’s practice because he lost his flight, and now a knee injury has forced him to miss the last two games in the summer league of Las Vegas.

Boston Celtic’s first-round pick got a bruised knee during his game against Philadelphia 76ers last Friday, where he had to leave the game after playing for seven minutes and scoring four points. Subsequently, MassLive announced that this contusion exacerbated an artery condition that he has had since college in both legs. This condition is called Popliteal artery entrapment syndrome (PAES), which is a rare vascular disease that affects the legs of young athletes. PAES is a blood flow reduction that leads to cramping and calf pain during exercise. Nonetheless, Williams confirmed to the Boston Globe that this issue has dissipated and is not a major concern.

The 20-year-old player told the Globe:

“Yeah, it was just a time-to-time thing, I haven’t been dealing with it for a while really. The last time was in the middle of my college season last year.”

Likewise, he confirmed that the Massachusetts team was aware of his issue before the NBA draft.

“Definitely, they asked me about it, every team is supposed to have concerns about what they’re investing money in, and I tell them it’s under control.”

Williams missed his first two games, but still, there's nothing to worry for the Celtics fans. This is just the summer league, where the teams take extra precautionary measures to take care of their rookies. The center’s future promises to be one full of success in this league among a bunch of young talent.
