When the Sabres announced defenseman Zach Bogosian had undergone successful hip surgery, they said he would need five to six months to recover.

That was six months ago today.

Bogosian, who has battled injuries for years, suffered setbacks during the summer and hasn’t even started practicing yet.

But Sabres general manager Jason Botterill said prior to Tuesday’s 4-3 overtime win against the San Jose Sharks he believes Bogosian, 29, will play this season.

“In my mind, there’s zero fear from that standpoint,” Botterill said inside KeyBank Center. “He’s back skating here right now. Very excited for where Zach is. Going over the type of procedure he had, it was a serious procedure, and Zach is a powerful individual, so you want him to come back (at full strength).”

The Sabres’ defense corps has been a major strength for three weeks, buoying their 7-1-1 start entering Tuesday.
