(Reuters) - Pittsburgh Pirates pitcher A.J. Burnett will undergo surgery on Friday to repair a fractured right orbital bone sustained in a bunting drill, the team said on Thursday.
Burnett was injured Wednesday when he fouled a bunt attempt into his face at the team's spring training field in Florida.
The right-handed pitcher, acquired last month in a trade with the New York Yankees, had preliminary examinations but had gone to Pittsburgh to be evaluated by specialists.
The Pirates said they had no word yet on a possible recovery time for Burnett, who was scheduled to face his former team, the Toronto Blue Jays, Sunday in the National League team's spring training opener.
