Boston Celtics star Kemba Walker is listed as "probable" for Wednesday's NBA clash with the Brooklyn Nets.

Celtics guard Walker missed Monday's 103-102 win over the Sacramento Kings due to a neck sprain.

Walker was hospitalised following a scary collision against the Denver Nuggets at the Pepsi Center on Friday.

The three-time All-Star – with his head down – bumped into team-mate Semi Ojeleye during the second quarter of Boston's 96-92 loss.

Walker had been averaging 22.6 points, 4.9 rebounds and 4.8 assists per game heading into the clash against the Nuggets.
