London, July 29 - England all-rounder Andrew Flintoff needed two more injections and has been sleeping with an ice-pack around his right knee to ensure his participation in the ongoing Ashes test series.

All the evidence suggests that the medical treatment is working and that the all-rounder will be ready to build on his man-of-the-match performance at Lord's by taking on Australia again at Edgbaston in the third Test starting Thursday.

An England team spokesman said that Flintoff was given a jab last Friday to lubricate his troublesome knee and received another dose of cortisone in the same area two days ago, The Times reported.

Flintoff, who needed three injections before Lord's, has also been wearing through the night a high-tech knee compression that is attached via tubing to a machine by his bedside that pumps water and ice around the joint to aid recovery.
