According to a report on ESPN.com, the Boston Celtics have agreed to trade Sam Cassell and cash to the Sacramento Kings in exchange for a future second-round pick. The Celtics currently have a league-maximum 15 players on their roster and this move would allow them to make an addition for the playoffs.

Cassell’s place on the Celtics came into question as talks of Stephon Marbury heated up this winter. Even though Cassell has not played since Game 5 of the NBA Finals on June 15, 2008, he told WEEI.com in January there was no agreement between him and the Celtics to step down in place of another player.

“No not at all. There’s nothing unwritten in this league,” he said. “I’m a part of this team til the end.”

The Kings could waive the 39-year-old veteran. Whether he winds up on the court in a uniform or the sidelines in a suit, Cassell is happy with his career.

“I’m here to do what this team (the Celtics) asks me to do,” Cassell said. “I’ve had a great career and I’m cool with it. Whatever the team needs from me. I want to coach. I’m almost 40-years-old … so it’s going to happen sooner or later. Either this year or next year.”

The NBA trade deadline is Thursday.
