If he needs surgery then it could be a while.
Alonzo Harris broke his hand August 25 last year and made the 53.
If surgery is not required he'll be back this week with a cast, so he shouldn't miss any more practice time and I'd expect him to play in the PS games. He might be inactive for a week or 2 until he rehabs after cast is removed.
Actually, as a gunner, he could use his cast to knock the jammer silly 😂.
