The Houston Rockets want Jeremy Lin back, and they're hoping to see him throw a few post passes to Dwight Howard.

Lin has signed an offer sheet with Houston, according to a person with direct knowledge of the move. The person spoke to The Associated Press today on condition of anonymity because the agreement with the New York Knicks' point guard was not announced.

Another person familiar with the negotiations says it's a three-year deal worth about $US25 million. The person, who spoke on condition of anonymity because the terms had not been announced, says the third year is worth about $US15 million.

Lin is a restricted free agent and New York is expected to match Houston's offer within the required three days.

The 6-foot-3 Lin was briefly in Rockets training camp before the season began. Houston waived him because they had already had Kyle Lowry and Goran Dragic on their roster.

The Knicks claimed Lin off waivers and he became an overnight sensation during a remarkable run in February. He averaged 14.6 points and 6.2 assists in 35 games before his season ended because of surgery to repair torn cartilage in his left knee.

Earlier, the Rockets waived Luis Scola via the amnesty clause. The one-time use of the amnesty clause allows Scola to leave without his remaining contract counting against the team's salary cap or luxury tax. Scola is due to make about $US21 million over the next three seasons.

A fan favorite in Houston, the 6-foot-9 Scola averaged 14.5 points and 7.7 rebounds in five seasons with the Rockets. Scola grabbed 2,984 rebounds with the Rockets to rank ninth on the team's career list.

The Rockets have torn apart their 2011-12 roster as they try for a deal that would pry Howard from Orlando. Cutting Scola allows Houston to absorb multiple undesirable contracts from Orlando in a potential deal.

Houston has been the most active team in the offseason, collecting assets and draft picks to build a package enticing enough to convince the Magic to trade Howard, a six-time All-Star and three-time defensive player of the year. On Tuesday, the Rockets completed a trade of point guard Kyle Lowry to Toronto for a lottery-protected first-round pick and a sign-and-trade deal that sent Marcus Camby to New York for two future second-round picks and three other players.

Before the draft, Houston traded forward Chase Budinger and center Samuel Dalembert in separate deals that netted two first-round picks. The Rockets were reportedly shopping the picks to move up in the draft, but eventually stayed put and used their three first-round draft picks on Connecticut guard Jeremy Lamb, Iowa State forward Royce White and Kentucky forward Terrence Jones.

Houston also is expected to sign Bulls center Omer Asik to an offer sheet. Earlier in free agency, Asik agreed to a three-year, $US25 million offer.

The Rockets turned back to Lin after the unrestricted free agent Dragic signed a four-year, $US30 million deal with Phoenix.

The 7-foot Asik was playing professionally in Turkey when he was picked by Portland in the second round of the 2008 draft and immediately traded to Chicago in a three-team deal. He played in 66 games last season, but only averaged 3.1 points, 5.3 rebounds and one block per game. Asik helped Turkey earn the silver medal at the 2010 FIBA world championship.
