The Iron, desperate for a win to boost their hopes of an end-of-season play-off place, ran out comfortable 3-0 winners against the already-relegated Robins, courtesy of goals from Paul Hayes, Cliff Byrne and Lansbury.
However the match ended on a sour note, as Cheltenham's Spanish full-back Yuri Berchiche, on loan from Tottenham, went in high, late and two-footed on Lansbury in injury-time.
The attacking midfielder needed to be rushed to hospital with a suspected broken leg. However, scans revealed the 18-year-old had not broken any bones, but had sustained damage to some medial knee ligaments.
Cheltenham boss Martin Allen was evidently less than chuffed with Berchiche’s actions - withdrawing him from the action before the game had even finished as the Robins voluntarily finished the match with 10 men.
The Gunners' youngster will now play no further part in Scunny’s season, including the play-offs, should they seal their place in the top six on Saturday when they face seventh-placed Tranmere on the final day of the league campaign.
