Rasheed Wallace will join the Knicks

Rasheed Wallace will officially become a Knick on Monday.

Wallace has told the Knicks he has elected to come out of retirement and join their training camp, according to an NBA source.

The 6-foot-11 Wallace, who worked out with the Knicks over the weekend, retired two years ago after a disappointing season with the Celtics. The Knicks are expected to announce the signing Monday at Media Day. The first practices begin Tuesday.

The tempestuous Wallace, 38, will become the fifth Knick over the age of 35, joining Jason Kidd, Marcus Camby, Kurt Thomas and Pablo Prigioni.
