Jacoby Ellsbury knows what you’re thinking.

Ellsbury left yesterday’s game in the second inning with what the Red Sox termed a “jammed right heel.” And after being sidelined for large chunks of two of the last three seasons, any time the center fielder is felled by an injury, concern follows about a potentially lengthy recovery.

Not to worry, Ellsbury insists.

“It’s going to be good,” he said after the Red Sox’ 7-6 win over the Philadelphia Phillies. “It just got a little tight, but it’s nothing of a concern. I’m sure we’ll look at it (today), but I mean, the way I feel, I feel good about it.”

Ellsbury tweaked his heel — actually, he said it was more of an ankle injury — while getting back to first base on a pickoff attempt in the first inning. He subsequently tried to steal second but was thrown out by Phillies catcher Humberto Quintero.

After playing defense in the second inning, Ellsbury was replaced by pinch-hitter Bryce Brentz. When the third inning began, right fielder Shane Victorino shifted to center.

Manager John Farrell reiterated that Ellsbury was removed from the game as a precaution. Ellsbury will be re-evaluated today in Fort Myers with the hope that he will be able to resume playing after tomorrow’s off day.
