Bristol City will again be without defender Lewin Nyatanga. The Robins will be without the centre-back for a further three weeks due to his persistent ankle injury. The Wales international has had an injection to try and cure the problem, but it will not be a quick solution. Manager Derek McInnes will be without the services of on-loan midfielder Sean Davis as a thigh strain keeps him out and the Bolton man is fighting to be fit for the weekend game at Middlesbrough.
Winger Kacaniklic is expected to have a better chance of involvement, however, despite being forced off 10 minutes from time with a leg problem. Manager Sean Dyche has options should Mariappa not make it, with Dale Bennett back in full training following his bout of concussion at West Ham while fellow defender Martin Taylor is also fit again after a broken toe. Otherwise, long-term injury victim Stephen McGinn (knee) is the only absentee as he continue his road to recovery.
Bristol City : 2.48
Watford : 2.72
Draw : 3.24
