The forward, 33, cost £250,000 when City bought him from Ipswich on August deadline day.
He's the second striker to leave this summer following the sale of Jon Parkin to Stoke, while Dean Windass is the club's only signing so far. The transfer of Roy O'Donovan from Cork City remains possible, though the Irish club's valuation of the player remains a stumbling block. Phil Brown will not be pursuing Seth Johnson due to the midfielder's current injury problems.
Three alterations have been made to the Tigers' fixture list. The game away to Scunthorpe on Saturday 24th November will now kick off at 12noon at the request of Humberside Police. Two games have also been moved for live coverage on Sky Sports. The trip to Blackpool has been moved back two days to Monday 3rd September, while the home game against Barnsley has been moved forward a day to Monday 22nd October.
