The Boston Celtics have emerged as a serious suitor for Courtney Lee after coach Doc Rivers met with the free-agent guard Saturday night, according to sources familiar with Boston’s thinking.

Sources told ESPN.com that the Celtics, in the wake of losing sharpshooter Ray Allen to the Miami Heat, have ratcheted up their pursuit of Lee as a possible replacement.

Lee averaged 11.4 points per game for the Houston Rockets last season and hit 40 percent of his 3-point attempts.
