Lees is expected to be out until 2016, as reported by the Sheffield Star, but Carvalhal has confirmed that the centre-back is making good progress.
CC: Tom Lees is working hard and wants to be back as soon as possible #swfcLIVE— Sheffield Wednesday (@swfc) December 23, 2015
Prior to his injury, Lees had been the only mainstay in Wednesday’s team this season.
The 25-year-old centre-back had been in brilliant form but he tore his hamstring while playing against Stoke City in the Capital One Cup.
Initially, Wednesday struggled in Lees’ absence, and they conceded four times in their first two games without him.
The Owls first drew 2-2 with Cardiff City, before losing 2-1 to Milton Keynes Dons.
However, Carvalhal’s side proved that they could cope without Lees in their latest outing – by beating Wolverhampton Wanderers 4-1.
That victory has moved the Yorkshire side back up to the edge of the play off spaces in the Championship table and while they have done okay without him, the Owls will no doubt want Lees back as soon as possible.
He has made 23 appearances for Wednesday so far this season, captaining the side on eight occasions and finding the net twice to date, proving his worth at both ends of the field.
