The Celtics lost James Posey to the open market, but today they were able to retain a couple of other free-agent reserves from their championship season.

The Celtics agreed to terms with guards Eddie House and Tony Allen to return, general manager Danny Ainge announced today. Both will get two-year contracts (though House's second year is a player option, according to an NBA source). House's deal was made using a portion of the team's $5.5 million mid-level exception. According to the source, House will make $2.7 million next season and $2.9 million the year after if he excercises his option.

House, who will enter his second season with the team, averaged 7.5 points and 19 minutes per game during the regular season, but those averages dropped to 2.5 points and just under 8 minutes in the postseason.

Allen agreed to a two-year guaranteed deal paying $2.5 million each year, according to a league source. Since the Celtics had Allen's Bird Rights, they didn't have to use the mid-level exception to re-sign him. Allen, who will enter his fifth season in green, averaged 6.6 points and just over 18 minutes per game during the regular season and 1.3 points in about 4 minutes per game in the playoffs.

Agent Mark Bartelstein, who also represents House, said the Celtics are interested in another of his free-agent clients: forward Devean George, who averaged 3.7 points per game for the Mavericks last season. The 31-year-old George played on three Lakers title teams.
