Game 1 of their Eastern Conference First Round Series against the Boston Bruins is Friday at TD Garden (7:30 p.m. ET; NBCSN, TSN, FS-D, NESN).
"Time-wise we were shooting for Round 2 if everything goes well," Zetterberg told the Red Wings website. "Increase intensity every day and hopefully in a couple days maybe I can do some more battling drills."
Zetterberg had back surgery on Feb. 21 after he was injured during the 2014 Sochi Olympics.
