Darren Helm just can’t catch a break. The injury-riddled forward didn’t skate Thursday because of a shoulder sprain, which will keep him out of these next two games (tonight in New Jersey, Saturday at home against Florida). General manager Ken Holland said an MRI showed fluid on the shoulder which suggests a sprain or strain. Holland said Helm will be re-evaluated Monday. “He’s not coming on the trip, he has a shoulder issue,” coach Mike Babcock said. “We’ll find out (later the extent). I just know he’s not coming on the trip.” Helm has provided a great boost to the Red Wings lineup since returning from 18 months worth of injuries (and the lockout) which limited him to two games (one regular season, one playoffs). Helm has seven goals and three assists for 10 points, in 15 games since returning averaging 16 minutes of ice time. While losing Helm at least for two games, the RedWings are getting a replacement. Todd Bertuzzi, who has missed the last five games with a shoulder issue, said he’s ready to return. With Henrik Zetterberg (herniated disc) and Pavel Datsyuk (concussion) out of the lineup, the loss of Helm makes three centers unavailable for Babcock. It’ll be interesting to see how Babcock reconfigures his lineup for Friday’s game in New Jersey.
