Jacoby Ellsbury was chipper in the Red Sox clubhouse just after 8 a.m. Wednesday. He looked tanned and happy and said he was going back to the trainer’s room for more evaluation of his sore right ankle and heel. The center fielder injured the foot sliding back into first base base on a pickoff attempt Sunday against the Phillies in Clearwater.

“We’re checking it out,’’ said Ellsbury. “There’s been some improvements, I guess.’’

A half-hour later, when the lineup was posted, Jackie Bradley Jr. was in the leadoff spot, playing center.

“It’s more precautionary than anything,’’ said manager John Farrell. “We fully expect him back in the lineup [Thursday night against the Twins].’’

According to Farrell, an examination of Ellsbury revealed, “no structural issue. Nothing with the Achilles’. He just made an awkward return to the bag. We’ll give it one more day.’’

Ellsbury is hitting .250 with no homers and one RBI in 44 at-bats this spring.

He was one of four regulars who didn’t play Wednesday because of an injury. The Sox know that David Ortiz (Achilles’, heel tendinitis) is going to start the season on the disabled list, and have been playing without Stephen Drew (concussion) since Drew was hit in the head by a pitch early in the spring. Shane Victorino rested Wednesday after jamming his wrist in pursuit of a fly ball Monday in Sarasota against the Orioles.

Victorino went for an MRI after the collision and was ruled OK to play. Drew is doing baseball activities, but occasionally still has concussion symptons at night.

“Same old, same old,’’ the shortstop said. “I’m cleared to do everything, but just a matter of symptoms. I’m getting better, but until it’s fully recovered I’m just doing my hitting and ground balls and therapy.’’

Farrell said Drew and Ortiz would accompany the team to New York for the season opener Monday in Yankee Stadium. Victorino is expected to play Thursday night. Just like Ellsbury.
