Atiba Lyons’s side welcome Manchester Giants to Ponds Forge tonight (7.30pm) before heading to Cheshire Phoenix on Sunday (5.30pm).
They will be particularly keen to avenge a surprise opening-night defeat by the Phoenix two weeks ago.
Sharks bounced back from that loss with road wins at Glasgow Rocks and Newcastle Eagles to get their campaign up and running.
To beat the Giants – who have Sharks’ former player Callum Jones on their roster again – Sheffield will hope to have American Jonathan Williams firing once again.
Williams missed just two shots in the win at Newcastle last Friday, including shooting a perfect seven from seven on the inside, on his way to 23 points, with six rebounds and four assists.
Williams’ tally included a decisive three inside the last five minutes that overturned a deficit and gave Sheffield the lead for good.
Lyons said of a guard with experience of playing in America, Poland and Belgium: “Jonathan is a versatile combo guard with a great resume in European basketball.
“He is a scorer with the ability to provide for his team-mates.
“He is a great system player but also has the ability to create for himself. I always felt he would be able to step in right away and contribute.”
