KISSIMMEE, Fla. -- Atlanta Braves outfielder Melvin Upton is expected to miss the rest of spring training because of inflammation in his left foot.

The team announced Upton's condition Friday after he underwent an X-ray and MRI exam.

Upton's foot will be placed in a short leg cast for two weeks, then in a walking boot from four to six weeks. The team said he will likely be able to resume baseball activities in early April, about the time the Braves are opening the regular season.

Upton was diagnosed with sesamoiditis, which is inflammation in the bone behind the ball of the foot.

The condition is a further setback for Upton, who is coming off two miserable seasons after signing a five-year, $75 million contract with the Braves.
