Nathan Horton couldn’t hide the smile from his face as he went through a full practice, and appeared ready to go for Game 1 of the playoffs starting Wednesday night against the Toronto Maple Leafs. Horton was wearing the white practice jersey and skating in his customary spot on the right wing alongside David Krejci and Milan Lucic at Tuesday’s practice at TD Garden after missing the last five games and 10 days of the regular season. The right winger indicated he’s probably in the lineup, but Bruins head coach Claude Julien was being a little more cautious in his assessment. “He practiced for the first time with the team today, and we’ll see how he is tomorrow before we make that decision,” said Claude Julien. “I thought he was playing really well before he was pulled out of the [Pittsburgh] game. Since then I think he’s been really excited about coming back. He skated well today, so right now, if he’s good to go, I hope to see the same player that left the ice [with an injury].” Horton sat out with an upper body injury suffered in a fight with Jarome Iginla on April 20 in a game where the nasty had seemingly returned to his game. Now Horton has a chance to pick up where he left off, and help out a sputtering Bruins offense as their third leading goal-scorer (13 goals) and one of four Boston skaters that finished with over 100 shots on goal. “I wished I didn’t get hurt and missed those last few games. We’re playing a little better, but we’re not scoring right now and we’re not putting teams away,” said Horton, who had put up seven goals in his final 12 games of the regular season before he suffered the injury. “But that’s in the past now, and we want to bury chances when we get to give us bigger leads."
