FOXBOROUGH, Mass. – The New England Revolution are getting healthy.

Jay Heaps said on Tuesday morning that Chris Tierney, Teal Bunbury, Jose Goncalves and Donnie Smith could all be available for this weekend’s meeting with FC Dallas after missing time recently.

Tierney has been sidelined the longest, missing the past four games with a left hamstring strain. He appeared set for a return last weekend against the Chicago Fire, but the Revs opted for precaution after the injury threatened to flare up again late in the week.

“I’m feeling better,” Tierney said on Tuesday. “It’s just one of those things where hamstrings are temperamental, so I’m just trying to be safe with it and make sure that I don’t do something bad that puts me out longer than I would like.

“I’m still progressing and hopefully will be involved in some way this week.”

Tierney was a full participant in training on Tuesday, as was Bunbury, who briefly returned from a hamstring strain with a substitute appearance against the LA Galaxy before missing last weekend’s meeting with the Fire.

Goncalves (who suffered a chest injury against LA) and Smith (who suffered a hamstring injury against Orlando) are also both very close to returning.

“Donnie is probably available at some point this week, but not out there yet,” Heaps said. “And Jose should be ready, as well. Both of those guys should be ready.”

The road is a bit longer for Charlie Davies, who’s missed the past three games after going down with a groin injury in the first half of the 1-1 draw with the Portland Timbers on April 27. Last year’s leading scorer returned to jogging last week, but has yet to join his teammates in training.

“Charlie is probably the furthest away,” Heaps said. “He had a significant injury and we’re going to go with him week-to-week right now. He’s still dealing with a lot.”
