Walker is considered questionable for Wednesday's game against the Cavaliers due to a sore left knee.
Walker sprained his ankle in a game during the middle of January, but this is the first we've heard of any recent knee issues. The 25-year-old played 33 minutes in Sunday's win over the Lakers, finishing with 12 points, seven rebounds, and six assists, though he shot just 3-of-14 from the field. In the event that Walker is held out or limited, Jeremy Lin and Brian Roberts would stand to see increased minutes.
