After suffering a concussion in the Bruins’ 6-5 win over the Flyers back on Jan. 22 in Philadelphia, Boston forward Nathan Horton has suffered a setback in his recovery.

Head coach Claude Julien, who has been hesitant to reveal Horton’s status in the past, revealed the news Friday during practice at TD Garden.

“He’s got some symptoms so he’s been pulled back,” he said. “He’s back to square one and we’re giving him some time here.”

Horton, who has missed the last six games, had a couple of light skates and has used the bike and other light exercises during in hopes of making a return to the ice sooner rather than later. But over the past couple of days, Horton has experienced the same concussion-like symptoms, including headaches, and his progression has taken a hit.

“Those symptoms — once they got back on the ice — they came back,” Julien said.

This is Horton’s second concussion in less than a year (eight months to be exact). The first came during the Stanley Cup Finals after Aaron Rome threw an elbow to Horton’s head in Game 3 of the Bruins’ series with Vancouver, which knocked him out for the entire playoffs. Horton returned to the Bruins’ lineup on opening night and compiled 32 points (17 goals, 15 assists) in 46 games prior to his latest injury.

With the annual Trade Deadline 17 days away, GM Peter Chiarelli and company will most likely look for some added depth to help fill Horton’s void. Potential candidates include Ray Whitney of Phoenix and Tuomo Ruutu of Carolina, just to name a couple.

For now, a timetable for any potential return of No. 18 for this season has not been set.
