3:32pm: Berman confirms (via Twitter) that the Rockets have waived Hayward. In addition to Hayward, Forbes, Brockman, and JaJuan Johnson, Houston has also released Shaun Livingston, according to Jonathan Feigen of the Houston Chronicle (via Twitter). Livingston was under contract for $3.5MM this season, but only $1MM was guaranteed.
With 19 players under contract, Houston has to release four players today in order to reduce their roster to the 15-man regular-season limit. We've heard previously that Gary Forbes and Jon Brockman are expected to be cut. If the team makes that official, and releases Hayward, it would still need to waive one more player.
Hayward, 25, has appeared in 68 total games for the Timberwolves and Thunder since being drafted 30th overall in 2010. He has averaged just 2.9 PPG on 35.4% shooting in his two NBA seasons. Like Forbes and Brockman, Hayward has a guaranteed contract for 2012/13, so the Rockets will need to eat some salary in order to waive him. The Marquette product is owed $1,174,080 for the coming season, and had a team option for $2.12MM, which it seems won't be picked up.
