Connolly suffered a knee injury in the first game of the competition against hosts Aalborg and didn’t participate in either of the two remaining games.
Head coach Aaron Fox said “The results of the scan was not very good news and it will keep Conns out long term. He will get the best medical treatment available and I know he will work on coming back stronger than ever. Conns is such a big piece of our group he will be tough to replace.
“Of course, with this news, added to our already long injury list we are looking at the market for a new player and have options currently being worked on.
“Without going into specifics, I am hopeful that we may have some better news that at least one of our injured guys will be ready ahead of the weekend. We will see how training goes today and tomorrow before deciding on our line-up for Saturdays game against Nottingham”
Steelers take on the Nottingham Panthers in their final Challenge Cup round-robin game at the Arena on Saturday evening. Face Off 7.00pm.
