MILWAUKEE (AP) — Bucks center John Henson had to celebrate his birthday Saturday on the bench against the Minnesota Timberwolves with a left leg injury.
Henson, who turned 23, said he thought he might have a high ankle sprain, though he is supposed to undergo more tests to determine exactly what's ailing him. It is unclear how long he might be out.
Henson leads Milwaukee in rebounding (8.0 per game) and blocks (2.25 per game). He is third on the team in scoring at 12.4 points.
The Bucks did get Larry Sanders back Friday after the shot-blocking center missed 25 games following surgery on his right thumb.
Injuries have been a problem all season for Milwaukee (6-23), which has the worst record in the NBA.
