Injury-plagued guard Steve Francis was placed on waivers Tuesday by the Memphis Grizzlies.

Francis, 31, had been negotiating a buyout since he was acquired on Dec. 24 from the Houston Rockets for a conditional second-round draft pick.

The three-time all-star neither played nor travelled with the Grizzlies, opting to practice only occasionally as he tried to recovered from surgery to repair a torn right quadriceps muscle suffered Dec. 15, 2007.

The procedure was performed last February.

Francis was chosen second overall by Vancouver in the 1999 NBA draft, but he refused to sign with the Grizzlies and coerced them into trading him to Houston.

With the Rockets, he earned co-rookies of the year honours, sharing the award with Elton Brand, and competed in three all-star games before injuries derailed his career. 

Francis has averaged 18.1 points, 6.0 assists, 5.6 rebounds and 37.6 minutes in 576 NBA appearances (543 starts) with the Rockets, Orlando Magic and New York Knicks.
