Watch the Match Highlights from the Gallagher Premiership fixture between Leicester Tigers and Worcester Warriors at Mattioli Woods Welford Road in Round 15 of the 21/22 season.
Tigers claimed a bonus-point 36-16 victory over the Warriors on Saturday.
But an interception try for Warriors, who had to cope for a period with 13 men after two yellow cards to front-row forwards earlier on, kept them in the game during a scrappy second period.
After consecutive league defeats by Wasps and Sale Sharks, the five-point return was assured when Tommy Reffell ran in his first try of the season, though Tigers closed the afternoon with 13 men after Olly Robinson and Saumaki were sin-binned in the final stages.
Liebenberg led the team out in the Gallagher Premiership Round 15 encounter in his first starting appearance since the Round 11 win over Harlequins, though Tigers were without five players with England on the opening weekend of the Six Nations.
The outcome was a fifth successive win in meetings with Worcester who were unable to add to their two previous victories at the venue.
