Chris Wilder reveals double injury doubt as Sheffield United captain has surgery
Sheffield United have injury doubts ahead of their trip to Coventry City where they will be without influential skipper Oliver Arblaster.
Manager Chris Wilder also admits there are “question marks” over forwards Kieffer Moore and Rhian Brewster, both of whom sat out the Blades’ previous game against fierce rivals Sheffield Wednesday, which United edged 1-0 to earn the Steel City bragging rights.
Arblaster, meanwhile, looks to be out for the season after the 20-year-old midfielder ruptured his ACL during the derby win over Wednesday.

Moore and Brewster both missed out against the Owls through injury but with two weeks over the international break to recover there is some hope that one, or both, may return in time for the trip to the Midlands as the Blades look to continue their good start to the Championship campaign.
United travel on the back of four straight wins in the league, having only lost two Championship games to date, against Leeds and Middlesbrough.
“There are still question marks going into the weekend,” said boss Chris Wilder, speaking at his pre-match press conference.
“What incredibly pleased me about our big win against Sheffield Wednesday was Femi [Seriki] coming onto the pitch, Sydie [Peck] coming onto the pitch and Ryan One.
“Brooksy [Andre Brooks] being a part of the squad, and the form of Tyrese Campbell. If they [Moore and Brewster] are not right or ready, then we’ll get on with it. It’s a no-excuse culture here.”
If Moore and Brewster aren’t available at the CBS Arena then it opens the door for Campbell to stake another claim to keep the shirt, having scored his third goal in the space of four games to win the derby last time out against Wednesday. Sydie Peck is in line to replace the injured Arblaster, who underwent surgery on his ACL injury over the break, while Tom Davies will be involved after returning to fitness following his troublesome hamstring issues.
