The Penguins have yet another injured player whose down time likely will be lengthy. Winger Chuck Kobasew will miss the next three to four weeks, coach Dan Bylsma said Tuesday. Kobasew got an unspecified injury Monday against Carolina when he absorbed a heavy check from Hurricanes defenseman Tim Gleason. Kobasew earned a roster spot and a contract after attending Penguins training camp on a professional tryout. He has two goals in 12 games and has spent time primarily on the right wing of the second and third lines. Third-line center Brandon Sutter also appeared to be injured (hand or wrist area) in the 3-1 win at Carolina. He remained in the game but did not practice Tuesday. Bylsma said Sutter had a “maintenance day,” which means he could be available to play tonight when Boston visits Consol Energy Center. Those injuries came one game after defenseman Rob Scuderi broke his left ankle when he came down awkwardly on his skates after being checked by Toronto’s David Clarkson. Scuderi, a defensive defenseman, is scheduled for surgery later this week — Bylsma said presumably the break will be stabilized with metal implants. There is no timetable yet for Scuderi, but it is expected to be weeks before he can return. Bylsma said James Neal, usually the right winger on the second line with Evgeni Malkin, remains out on a “week-to-week” basis because of an unspecified injury. The other longer-term absence is to backup goaltender Tomas Vokoun, who is expected to miss at least two more months while he is on blood-thinners after surgery for a blood clot. One injured player, however, could be nearing a return. “Beau Bennett skated at length and looks to be maybe returning to practice later this week. No definitive date,” Bylsma said. Bennett, who has missed the past seven games because of an unspecified injury, skated before practice with conditioning coach Mike Kadar.
