Milwaukee Bucks head coach Mike Budenholzer offered reassurance on the severity of Giannis Antetokounmpo's knee injury after missing Sunday's 104-101 win over the Phoenix Suns.

Antetokounmpo sustained the injury after a clash of knees forced him out of Friday's 128-99 win over the Miami Heat in the first quarter after playing only six minutes.

Budenholzer was unable to offer much detail after Friday's game, but provided more clarity following Sunday's win, which was Milwaukee's 14th in a row.

"It's enough where he can't play today, but I think we're also confident that this is a fairly common occurrence in our league," Budenholzer told reporters.

"You hit knees, you knock, sometimes it takes a day or two and it's really nothing more than that. The level of conversations have all been along that line."

The Bucks' 14-game win streak is the longest in the NBA this season, with the 43-17 side behind only the Boston Celtics (44-17).

MVP candidate Antetokounmpo, who recently spent time out with a wrist injury, has been a key part of the Bucks' success this campaign.

Antetokounmpo (31.3) is behind only Luka Doncic (33.2), Joel Embiid (33.1) and Damian Lillard (31.4) for points per game this season and is second for rebounds, averaging 12.0 per game behind only Domantas Sabonis (12.3).

Jrue Holiday top scored with 33 points against the Suns, while center Brook Lopez made a strong contribution with 22 points and 13 rebounds.
