Headley was not available off the bench Thursday due to back spasms, Bryan Hoch of MLB.com reports.
EDGE Analysis
It was initially thought that the Yankees were merely giving the veteran the day off Thursday, but now it is being reported that Headley is battling some back issues. Hoch adds that the Yankees are unsure whether Headley will be ready to return in time for Friday's series opener against the Rangers, but more information on the situation should be made available during the day. Ronald Torreyes, who started at third base Thursday, would be the likeliest candidate to fill in for Headley should he sit out again.
