No. 1 Duke says freshman star Zion Williamson is day to day with a mild right knee sprain.

Team spokesman Mike DeGeorge said Thursday night that Williamson is progressing as expected after he injured his knee when his left shoe ripped apart as he slipped while dribbling during the first minute of Wednesday night’s loss to No. 8 North Carolina.

The 280-pound Williamson is one of the most powerful players in the game, and he tried to plant with his left foot as his right foot was slipping. The blue rubber sole ripped loose from the white shoe, and Williamson’s foot came all the way through the large gap.

Nike said in a statement that it was “concerned” and wished Williamson a speedy recovery. It said the incident was an “isolated occurence” but was “working to identify the issue.”

Boeheim strikes, kills pedestrian: Longtime Syracuse coach Jim Boeheim struck and killed a man standing along an interstate late Wednesday night as he tried to avoid hitting the man’s disabled vehicle, police said.

Syracuse police say 51-year-old Jorge Jimenez was an occupant in a vehicle with three others when they lost control and hit a guardrail before midnight Wednesday on I-690 in Syracuse.

Boeheim struck Jimenez as he stood on the side of the road while trying to avoid the vehicle in the middle of the highway.

“I am heartbroken that a member of our community died as the result of last night’s accident,” Boeheim said in a statement.

He said he would not comment further “out of respect for those involved.”

Police said Boeheim, 74, is cooperating with the investigation.

Police said sobriety tests administered to Boeheim and the unidentified driver of the other vehicle were negative for any signs of impairment. Onondaga County (N.Y.) District Attorney William Fitzpatrick said he has known Boeheim for 40 years and that the coach doesn’t drink.
