The Bruins held their first practice of the postseason Tuesday at TD Garden, and the lines featured the return of Nathan Horton  and some evidence that Rich Peverley  could be in line for a healthy scratch in Game 1 against the Maple Leafs.
Horton has been skating since last week but has been out of game action since suffering an upper-body injury in a fight against Jarome Iginla on April 20. He skated on his normal line with David Krejci  and Milan Lucic  on Tuesday.
Peverley, meanwhile, practiced in a green jersey, which is worn by players not skating on the top four lines. The lines were as follows:
Lucic – Krejci – Horton
Marchand – Bergeron – Seguin
Daugavins – Kelly – Jagr
Paille – Campbell – Thornton
Extra forwards: Peverley, Soderberg, Pandolfo
Following the practice, Claude Julien  said that the lines from Tuesday’s skate are no sure thing to be the lines for Game 1 on Wednesday night.
“That doesn’t mean that’s my lineup, just so you guys know,” he said. “I put some lines together today, but my lineup has not been done yet. It will get finalized tomorrow.”
