Former NBA player Glen Davis has issued a warning to New Orleans Pelicans forward Zion Williamson, noting that the rookie must manage his weight or risk ending his career early like him.

“That’s one of the reasons why I stopped playing was because of my weight,” Davis said, per TMZ. “He [Zion Williamson] has to get his weight under control.”

Davis weighed up to 289 lbs during his playing days. He blamed his weight for the ankle and foot issues he suffer in 2015, which eventually ended his NBA career early.

Williamson, meanwhile, is listed at 6-foot-7 and 285 lbs. This was his main asset in high school and college, as nobody has ever seen a man that big with supreme athletic gifts.

However, when he turned pro, fans and analysts quickly saw Williamson's weight and athletic play style as a possible hindrance to maintaining a long playing career. The first overall draft pick of the 2019 NBA Draft is still out recovering from meniscus surgery, and he is expected to be out until December.

Apart from his warning, Davis also went into the specifics on what Williamson should do:

“He might have to lose some muscle mass, but other that, he should be OK,”  said the former NBA big man who was nicknamed “Big Baby.”

Williamson has probably heard tons of advice about his weight, but Davis' words could be the most valuable among the lot.
