OWEN Burrows has revealed that former 2000 Guineas runner-up Massaat faces a lengthy spell on the sidelines after meeting with a setback.

After having made a winning return last season in the Group 2 Hungerford Stakes at Newbury, the five-year-old son of Teofilo finished third in the Group 1 Prix du Moulin at Chantilly before finding only Limato too strong in what was to be his final start of the campaign, in the Group 2 Challenge Stakes at Newmarket in October.
